-------------------------------------
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.
