Chia-Ping Tsai updated HBASE-19496:
-----------------------------------
Attachment: HBASE-19496.addendum.patch
If a cp is loaded by rs and region, the duplicate cp name will appear in rs
report. The previous RegionLoad removes the duplicate name in the getter. The
addendum takes the same prescription. BTW, the trivial change in endpoint
module is used to trigger the QA since the failed tests is in endpoint module.
> Reusing the ByteBuffer in rpc layer corrupt the ServerLoad and RegionLoad

> {{ServerLoad}} and {{RegionLoad}} store the pb object internally but the
> bytebuffer of pb object may be reused in rpc layer. Hence, the {{ServerLoad}}
> and {{RegionLoad}} which saved by {{HMaster}} will be corrupted if the
> bytebuffer backed is modified.
> This issue doesn't happen on branch-1.
> # netty server was introduced in 2.0 (see HBASE-17263)
> # reusing bytebuffer to read RPC requests was introduced in 2.0 (see
> HBASE-15788)
