Hi,
When I execute command of 'list' in hbase shell, it told me that the
HRegioninfo was null or empty in -ROOT-.
Did the -ROOT- table value got corrupted or any other reasons cause this
problem?
Here's the info from the 'list' and 'hbck' tool:
--------------------------------------------------------------------------------------------------------------------
hbase(main):001:0> list

integer but got as null.Hence setting to default value 1048575
