Viraj Jasani commented on HBASE-26021:
--------------------------------------
{quote}do we need to test upgrade from 1.7.0 (if someone already use it) to
1.7.1 (1.7.0.1)
{quote}
Yeah, nice one [~reidchan]. Specifically table state I think i.e disable one
table in 1.7.0 cluster, keep it that way, upgrade to 1.7.1 and observe the
state. What if table state is not compatible? Does this mean we should
revoke/withdraw 1.7.0 and remove mirrors? Is it considered valid for an already
released version? Or we should consider some other alternatives?

> 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 meta*" and "*\n hbase namespace*"
