| # This file provides a variety of site-specific settings to control Drill |
| # launch settings. These are settings required when launching the Drillbit |
| # or sqlline processes using Java. Some settings are for both, some for one |
| # or the other. |
| # |
| # Variables may be set in one of four places: |
| # |
| # Environment (per run) |
| # drill-env.sh (this file, per site) |
| # distrib-env.sh (per distribution) |
| # drill-config.sh (Drill defaults) |
| # |
| # Properties "inherit" from items lower on the list, and may be "overridden" by items |
| # higher on the list. In the environment, just set the variable: |
| # |
| # export FOO=value |
| # |
| # To support inheritance from the environment, you must set values as shown below: |
| # |
| # export FOO=${FOO:-"value"} |
| # |
| # or a more specialized form. |
| |
| # Amount of total memory for the Drillbit process. This value is defined as the limit |
| # that the startup script will try to enforce on the Drill JVM. The values can be |
| # defined in terms of percentage of the available system memory, or in terms of actual |
| # values, similar to how we define the actual JVM memory parameters like Heap Size. |
| # There is no default and depends on how much can be allotted on a machine. |
| # This enables Drill's memory auto-configuration logic to kick in, and should be unset |
| # if the intent is to not use the auto-configuration. |
| |
| #export DRILLBIT_MAX_PROC_MEM=${DRILLBIT_MAX_PROC_MEM:-"13G"} |
| |
| # Amount of heap memory for the Drillbit process. Values are those supported by |
| # the Java -Xms option. The default is 4G. |
| |
| #export DRILL_HEAP=${DRILL_HEAP:-"4G"} |
| |
| # Maximum amount of direct memory to allocate to the Drillbit in the format |
| # supported by -XX:MaxDirectMemorySize. Default is 8G. |
| |
| #export DRILL_MAX_DIRECT_MEMORY=${DRILL_MAX_DIRECT_MEMORY:-"8G"} |
| |
| # Native library path passed to Java. Note: use this form instead |
| # of the old form of DRILLBIT_JAVA_OPTS="-Djava.library.path=<dir>" |
| # The old form is not compatible with Drill-on-YARN. |
| |
| # export DRILL_JAVA_LIB_PATH="<lib1>:<lib2>" |
| |
| # Value for the code cache size for the Drillbit. Because the Drillbit generates |
| # code, it benefits from a large cache. Default is 1G. |
| |
| #export DRILLBIT_CODE_CACHE_SIZE=${DRILLBIT_CODE_CACHE_SIZE:-"1G"} |
| |
| # Provide a customized host name for when the default mechanism is not accurate |
| |
| #export DRILL_HOST_NAME=`hostname` |
| |
| # Base name for Drill log files. Files are named ${DRILL_LOG_NAME}.out, etc. |
| |
| # DRILL_LOG_NAME="drillbit" |
| |
| # Location to place Drill logs. Set to $DRILL_HOME/log by default. |
| |
| #export DRILL_LOG_DIR=${DRILL_LOG_DIR:-$DRILL_HOME/log} |
| |
| # Location to place the Drillbit pid file when running as a daemon using |
| # drillbit.sh start. |
| # Set to $DRILL_HOME by default. |
| |
| #export DRILL_PID_DIR=${DRILL_PID_DIR:-$DRILL_HOME} |
| |
| # Default (Standard) CGroup Location: /sys/fs/cgroup |
| # Specify the cgroup location if it is different from the default |
| #export SYS_CGROUP_DIR=${SYS_CGROUP_DIR:-"/sys/fs/cgroup"} |
| |
| # CGroup to which the Drillbit belongs when running as a daemon using drillbit.sh start . |
| # Drill will use CGroup for CPU enforcement only. |
| |
| # Unset $DRILLBIT_CGROUP by default |
| #export DRILLBIT_CGROUP=${DRILLBIT_CGROUP:-"drillcpu"} |
| |
| # Custom JVM arguments to pass to the both the Drillbit and sqlline. Typically |
| # used to override system properties as shown below. Empty by default. |
| |
| #export DRILL_JAVA_OPTS="$DRILL_JAVA_OPTS -Dproperty=value" |
| |
| # As above, but only for the Drillbit. Empty by default. |
| |
| #export DRILLBIT_JAVA_OPTS="$DRILLBIT_JAVA_OPTS -Dproperty=value" |
| |
| # Process priority (niceness) for the Drillbit when running as a daemon. |
| # Defaults to 0. |
| |
| #export DRILL_NICENESS=${DRILL_NICENESS:-0} |
| |
| # Custom class path for Drill. In general, you should put your custom libraries into |
| # your site directory's jars subfolder ($DRILL_HOME/conf/jars by default, but can be |
| # customized with DRILL_CONF_DIR or the --config argument. But, if you must reference |
| # jar files in other locations, you can add them here. These jars are added to the |
| # Drill classpath after all Drill-provided jars. Empty by default. |
| |
| # custom="/your/path/here:/your/second/path" |
| # if [ -z "$DRILL_CLASSPATH" ]; then |
| # export DRILL_CLASSPATH=${DRILL_CLASSPATH:$custom} |
| # else |
| # export DRILL_CLASSPATH="$custom" |
| # fi |
| |
| # Extension classpath for things like HADOOP, HBase and so on. Set as above. |
| |
| # EXTN_CLASSPATH=... |
| |
| # Note that one environment variable can't be set here: DRILL_CONF_DIR. |
| # That variable tells Drill the location of this file, so this file can't |
| # set it. Instead, you can set it in the environment, or using the |
| # --config option of drillbit.sh or sqlline. |
| |
| #----------------------------------------------------------------------------- |
| # The following are "advanced" options seldom used except when diagnosing |
| # complex issues. |
| # |
| # The prefix class path appears before any Drill-provided classpath entries. |
| # Use it to override Drill jars with specialized versions. |
| |
| #export DRILL_CLASSPATH_PREFIX=... |
| |
| # Enable garbage collection logging in the Drillbit. Logging goes to |
| # $DRILL_LOG_DIR/drillbit.gc. A value of 1 enables logging, all other values |
| # (including the default unset value) disables logging. |
| |
| #export SERVER_LOG_GC=${SERVER_LOG_GC:-1} |
| |
| # JVM options when running the sqlline Drill client. |
| # These are used ONLY in non-embedded mode; these |
| # are client-only settings. (The Drillbit settings are used when Drill |
| # is embedded.) |
| |
| #export SQLLINE_JAVA_OPTS="" |
| |
| # Arguments passed to sqlline (the Drill shell) at all times: whether |
| # Drill is embedded in Sqlline or not. |
| |
| #export DRILL_SHELL_JAVA_OPTS="..." |
| |
| # Location Drill should use for temporary files, such as downloaded dynamic UDFs jars. |
| # Set to "/tmp" by default. |
| # |
| # export DRILL_TMP_DIR="..." |
| |
| # Block to put environment variable known to both Sqlline and Drillbit, but needs to be |
| # differently set for both. OR set for one and unset for other. |
| # |
| # if [ "$DRILLBIT_CONTEXT" = "1" ]; then |
| # Set environment variable value to be consumed by Drillbit |
| # else |
| # Set environment variable value to be consumed by Sqlline |
