Hi, It seems it was fine when the cluster is first started, but after running under some heavy load for a while, it stops showing any of those RPC handler tasks.
We have seen this on our newly upgraded 94.26, and also 1.0. It works fine in 0.94.7 before. Other people also reported same issue on 0.98.6-cdh5.2.0, links here <https://mail-archives.apache.org/mod_mbox/hbase-user/201507.mbox/%3CCALPvCiBofxPY1TJUB6M18A_=ky_bsovg6wcq6jtrmegbda5...@mail.gmail.com%3E> It seems a regression? Anyone has any idea? Thanks Tian-Ying
