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) -- This message was sent by Atlassian JIRA (v6.4.14#64029)
