Viraj Jasani commented on HBASE-26021:
--------------------------------------
The above Exception comes up regardless of the upgrade mechanism i.e rolling
upgrade (using RS followed by HM) or complete cluster shutdown. We can
reproduce above issue locally:
# Bring up 1.7 cluster, start one RS from 2.4 bits and meta, namespace regions
will be moved to 2.4 RS. We will observe above issue.
# Bring up 1.7 cluster, create some tables, ingest some data, bring the
cluster down. Start 2.4 cluster and master we can observe above issue is master
logs.
For #2, logs would be:

> HBase 1.7 to 2.4 upgrade issue
> ------------------------------
>
> Key: HBASE-26021
> URL: https://issues.apache.org/jira/browse/HBASE-26021
> Project: HBase
> Issue Type: Bug
> Affects Versions: 1.7.0, 2.4.4
> Reporter: Viraj Jasani
> Priority: Major
>
> As of today, if we bring up HBase cluster using branch-1 and upgrade to
> branch-2.4, we are facing issue while parsing namespace from HDFS fileinfo.
> Instead of "*hbase:meta*" and "*hbase:namespace*", parsing using ProtobufUtil
> seems to be producing "*\n hbase:\n meta*" and "*\n hbase:\n namespace*"
