| This directory contains the hdfs extensions needed to make rocksdb store |
| files in HDFS. |
| |
| It has been compiled and testing against CDH 4.4 (2.0.0+1475-1.cdh4.4.0.p0.23~precise-cdh4.4.0). |
| |
| The configuration assumes that packages libhdfs0, libhdfs0-dev are |
| installed which basically means that hdfs.h is in /usr/include and libhdfs in /usr/lib |
| |
| The env_hdfs.h file defines the rocksdb objects that are needed to talk to an |
| underlying filesystem. |
| |
| If you want to compile rocksdb with hdfs support, please set the following |
| environment variables appropriately (also defined in setup.sh for convenience) |
| USE_HDFS=1 |
| JAVA_HOME=/usr/local/jdk-7u79-64 |
| LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/jdk-7u79-64/jre/lib/amd64/server:/usr/local/jdk-7u79-64/jre/lib/amd64/:./snappy/libs |
| make clean all db_bench |
| |
| To run dbbench, |
| set CLASSPATH to include your hadoop distribution |
