Subject [jira] [Commented] (HBASE-16938) TableCFsUpdater maybe failed due to no write permission on peerNode
Date Tue, 01 Nov 2016 03:59:58 GMT

    [ https://issues.apache.org/jira/browse/HBASE-16938?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15624262#comment-15624262

Heng Chen commented on HBASE-16938:
-----------------------------------

The patch looks OK to me.  It extracts the updater to be one tool,  so we could run it alone
and no harm to current logic.  :)

> After HBASE-11393, replication table-cfs use a PB object. So it need copy the old string
config to new PB object when upgrade cluster. In our use case, we have different kerberos
for different cluster, etc. online serve cluster and offline processing cluster. And we use
a unify global admin kerberos for all clusters. The peer node is created by client. So only
global admin has the write  permission for it. When upgrade cluster, HMaster doesn't has the
write permission on peer node, it maybe failed to copy old table-cfs string to new PB Object.
I thought it need a tool for client to do this copy job.
