| /** |
| * The classes under this package were copied from Apache Hadoop and modified |
| * to avoid certain issues during tests. The copied classes override the |
| * Apache Hadoop dependency versions during tests. |
| * |
| * HttpServer2 class was copied to avoid Jetty 9.4 dependency issues. Since |
| * Solr uses Jetty 9.4, Hadoop integration tests needs to use Jetty 9.4 as |
| * well. The HttpServer2 class should be removed when Hadoop is upgraded to |
| * 3.3.0 due to HADOOP-16152 upgrading Hadoop to Jetty 9.4. |
| * |
| * The classes BlockPoolSlice (HDFS-14251), DiskChecker, FileUtil, HardLink, |
| * NameNodeResourceChecker, and RawLocalFileSystem were copied to avoid |
| * issues with running Hadoop integration tests under the Java security |
| * manager. Many of these classes use org.apache.hadoop.util.Shell |
| * which shells out to try to do common filesystem checks. |
| * |
| * Overtime these classes should be removed as upstream fixes to Apache |
| * Hadoop are made. When the Apache Hadoop dependency is upgraded in |
| * Solr, the classes should be compared against that version. |
