liang xie commented on HBASE-5076:
----------------------------------
After enable hbase-shell debug log, found there's an infinite loop in metaScan
method for some special tablenames:
{code}
do {
...
if (rrs == null || rrs.length == 0 || rrs[0].size() == 0) {
break; //exit completely
}
...
startRow = callable.getHRegionInfo().getEndKey();
...
} while (Bytes.compareTo(startRow, HConstants.LAST_ROW) != 0);
{code}
Maybe a feasible fix is to filter some system-reserved tablenames in
HTableDescriptor.isLegalTableName.
I can try to give a trivial patch if you or other experts agree:)
> HBase shell hangs when creating some 'illegal' tables.

> Key: HBASE-5076
> URL: https://issues.apache.org/jira/browse/HBASE-5076
> Project: HBase
> Issue Type: Bug
> Components: shell
> Affects Versions: 0.92.0
> Reporter: Jonathan Hsieh
> Priority: Minor
>
> In hbase shell. These commands hang:
> {code}
> create 'hbase.version','foo'
> create 'splitlog','foo'
> {code}
> Interestingly
> {code}
> create 'hbase.id','foo'
> create existingtablename, 'foo'
> create '.META.','foo'
> create '-ROOT-','foo'
> {code}
> are properly rejected.
> We should probably either rename to make the files illegal table names
> (hbase.version to .hbase.version and splitlog to .splitlog) or we could add
> more special cases.
