--------------------------------------
Summary: Reusing the ByteBuffer in rpc layer corrupt the
ServerLoad and RegionLoad
Key: HBASE-19496
URL: https://issues.apache.org/jira/browse/HBASE-19496
Project: HBase
Issue Type: Bug
Reporter: Chia-Ping Tsai
Assignee: Chia-Ping Tsai
Priority: Blocker
Fix For: 2.0.0-beta-1
{{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)
