keith-turner opened a new issue #1629:
URL: https://github.com/apache/accumulo/issues/1629
The changes in #1605 introduced a compaction manager and multiple compaction
services. Currently the compaction manager has a single thread that goes
through all tablets and does the following.
1. Determine which compaction service a tablet should use
2. Select files to compact
3. Make compaction plan
Steps 2 and 3 occur in the compaction service. Step 1 happens in the
compaction manager. If Step 2 is taking a long time in compaction service A,
then it could prevent compaction service B from getting work. Could possibly
introduce some concurrency to avoid this problem.
