             Summary: Enable CompactionTool executions on non-HDFS filesystems
                 Key: HBASE-24111
                 URL: https://issues.apache.org/jira/browse/HBASE-24111
             Project: HBase
          Issue Type: Improvement
          Components: Compaction, mapreduce, tooling
            Reporter: Peter Somogyi
            Assignee: Peter Somogyi
             Fix For: 3.0.0, 2.3.0, 2.4.0, 2.2.5


CompactionTool on non-HDFS filesystems does not work because the used filesystems are mixed up. To collect the StoreFiles the {{Filesystem.get(conf)}} method is used instead of relying on the root dir filesystem.

With YARN the delegation tokens are not handled correctly with a different filesystem and the mappers only get delegation token for the staging directory's filesystem. 

Another issue is in MapReduce mode when YARN is used. In this case the TMP directory ({{hbase.tmp.dir}}) is created under {{yarn.nodemanager.local-dirs}} but this directory is created (even on HDFS a regular user can't create this directory) on the Storefile's filesystem where a local filesystem temp directory shouldn't be used.

In this ticket I plan to clean up the used filesystems, remove the custom temp directory (use the regions' .tmp directory) and collect delegation tokens for staging dir + store dir paths' FileSystems.
