stack commented on HBASE-7191:
------------------------------
Back looking at this issue. This is what I get if I remove the hbase.version
file:
{code}
org.apache.hadoop.hbase.util.FileSystemVersionException: HBase file layout
needs to be upgraded. You have version null and I want version 8. Consult
http://hbase.apache.org/book.html for further information about upgrading
HBase. Is your hbase.rootdir valid? If so, you may need to run 'hbase hbck
-fixVersionFile'.

After commit of HBASE-22688 this morning, the fix is running the filesystem
command from hbck2 with the -fix option. It restores the hbase.version file.
{code}$
HBASE_CLASSPATH_PREFIX=../hbase-operator-tools/hbase-hbck2/target/hbase-hbck2-1.0.0-SNAPSHOT.jar
bin/hbase org.apache.hbase.HBCK2 filesystem -fix{code}
It does NOT put back the hbase.id file. Launching the hbase process creates a
new one if missing which is probably not ideal; should probably try and find
old cluster id and put that back rather than create a new one. hbase cluster id
doesn't seem critical so will leave it for now until someone complains.
Meantime let me close out this issue with a patch that fixes the message that
is spewed when hbase.version is missing.
> HBCK - Add offline create/fix hbase.version and hbase.id

> Project: HBase
> Issue Type: Improvement
> Components: hbck
> Affects Versions: 0.94.1
> Reporter: Enis Soztutar
> Assignee: xufeng
> Priority: Major

>
> One of our clients run into a problem, in which they have the hbase.root.dir,
> and cluster data, but their hbase.id and hbase.version files are corrupted.
> HMaster creates those on start, but not if there is already existing data.
> We can add smt like --fixIdFile, and ability for HBCK to do some offline
> repairs for the version file.
