Anoop Sam John commented on HBASE-5631:
---------------------------------------

One point is with out the .tableinfo file in HDFS, HBCK can not fix HDFS integrity issues.
For recreating the .tableinfo file in HDFS we need the HTD instance of the table. Well we can try getting this from the Master or RSs. In RS side the HRegion will have HTD instances. Also in Master, it might be already cached in FSTableDescriptors before the file actually got missed. We can try getting from any where possible (Hope from some where we will get HTD) and recreate the .tableinfo file. One point is this can work only in online mode.

And if the .tableinfo file is missing the offline mode fixes wont work also.

Pls validate my analysis
