Anoop Sam John commented on HBASE-4379:
---------------------------------------
{code}
public boolean checkRegionChain(TableIntegrityErrorHandler handler) throws
IOException {
+ // When table is disabled no need to check for the region chain. Some of
the regions
+ // accidently if deployed, this below code might report some issues like
missing start
+ // or end regions or region hole in chain and may try to fix which is
unwanted.
+ if (disabledTables.contains(this.tableName.getBytes())) {
+ return true;
+ }
{code}
When the table is disabled, the regions in this need not undergo the check for
consistency I feel. Suppose a table is disabled and 1st and 3rd regions of it
are online. The HBCK will fix this making the regions offline. But this
checkRegionChain can report a hole between the 2 regions and may try to fix
this creating a new region. I just added this check at this place. May be at a
broader scope need to add. Pls give you feedback. I will debug more and add
changes if needed.
