Vladimir Rodionov created HBASE-12190:
-----------------------------------------
Summary: Split thread pool larger than one results in fatal
failure during region splits
Key: HBASE-12190
URL: https://issues.apache.org/jira/browse/HBASE-12190
Project: HBase
Issue Type: Bug
Components: regionserver
Affects Versions: 2.0.0
Reporter: Vladimir Rodionov
I have been playing with different sizes for long/short compaction and split
thread poll sizes. It is definitely clear, that any size of split thread pool
large than 1 (one) results in a fatal errors during region splits.
Here is the log file snippet of a local test case :
