[GitHub] [hbase] kai33 opened a new pull request #1251: HBASE-23950.
Backport HBASE-22480 to branch-2.1
kai33 opened a new pull request #1251: HBASE-23950. Backport HBASE-22480 to branch-2.1
URL: https://github.com/apache/hbase/pull/1251
Link to Jira:
https://issues.apache.org/jira/browse/HBASE-23950
My HBase 2.0/2.1 cluster experienced severe performance drop after running reversed scans for days. When debug into regionserver logs, it appears the bucket cache is full for every ~100 ms and its eviction can't work properly because ref count has become negative:
```
(every ~100 ms)
Free started because "Full!"
This block AAA is still referred by -1 readers. Can not be freed now
This block BBB is still referred by -2 readers. Can not be freed now
This block CCC is still referred by -3 readers. Can not be freed now
...
This block ... is still referred by (negative number) readers. Can not be freed now
```
There have been patch HBASE-22480 addressing this ref count problem in 2.2+. I'd like to backport it to 2.1 (understand that 2.0 is EOL)
