Change subject: IMPALA-7450. Set thread name during refresh/load operations ...................................................................... IMPALA-7450. Set thread name during refresh/load operations This adds a small utility class for annotating the current thread's name during potentially long-running operations such as refresh/load. With this change, jstack output now includes useful thread names like: During startup: "main [invalidating metadata - 128/428 dbs complete]" While loading a fresh table: "pool-4-thread-12 [Loading metadata for: foo_db.foo_table] [Loading metadata for all partition(s) of foo_db.foo_table]" Pool refreshing metadata for a particular path: "pool-23-thread-5 [Refreshing file metadata for path: hdfs://nameservice1/path/to/partdir..." Tests: Verified the patch manually by jstacking a catalogd while performing some workload. Also added a simple unit test to verify the thread renaming behavior.
