------------------------------------
Summary: Disable hdfsEncryptionShims cache during query-based
compaction
Key: HIVE-24168
URL: https://issues.apache.org/jira/browse/HIVE-24168
Project: Hive
Issue Type: Bug
Reporter: Karen Coppage
Assignee: Karen Coppage
Hive keeps a cache of encryption shims in SessionState (Map<URI,
HadoopShims.HdfsEncryptionShim> hdfsEncryptionShims). Each encryption shim in
the cache stores a FileSystem object.
After compaction where the session user is not the same user as the owner of
the partition/table directory, we close all FileSystem objects associated with
the user running the compaction, possibly closing an FS stored in the
encryption shim cache. The next time query-based compaction is run on a
table/partition owned by the same user, compaction will fail in MoveTask[1]
since the FileSystem stored in the cache was closed.
This change disables the cache during query-based compaction (optionally;
default: disabled).
