Yu Li commented on HBASE-19320: ------------------------------- bq. Can we also make the netty rpc server default for 2.0? Yes, I thought this was the plan... We've been running netty rpc server in production for more than a year and went through two big sale with it, everything looks good (although we still use the netty3 version for some historical reason, I believe netty4 would be better). Just let me know what we could help/need to do to make it default, thanks. > document the mysterious direct memory leak in hbase > ---------------------------------------------------- > > Key: HBASE-19320 > URL: https://issues.apache.org/jira/browse/HBASE-19320 > Project: HBase > Issue Type: Improvement > Affects Versions: 2.0.0, 1.2.6 > Reporter: huaxiang sun > Assignee: huaxiang sun > Attachments: Screen Shot 2017-11-21 at 4.43.36 PM.png, Screen Shot > 2017-11-21 at 4.44.22 PM.png > > > Recently we run into a direct memory leak case, which takes some time to > trace and debug.
