Ted Yu commented on HBASE-4377:
-------------------------------
@Sebastian:
== shouldn't be used in comparing strings:
{code}
+ if(Bytes.toString(getTableName())==""){
+ byte [] newTableName = HRegionInfo.getTableName(this.getRegionName());
+ System.out.println(Bytes.toString(newTableName)+": .regioninfo doesn't
have tableName value, but we are getting it from regionName :)");
+ this.setTableName(newTableName);
+ }
{code}
You can use:
{code}
if (getTableName() == null || getTableName().length == 0) {
{code}
System.out.println should be replaced by LOG.debug()
> [hbck] Offline rebuild .META. from fs data only.

> In a worst case situation, it may be helpful to have an offline .META.
> rebuilder that just looks at the file system's .regioninfos and rebuilds meta
> from scratch. Users could move bad regions out until there is a clean
> rebuild.
> It would likely fill in region split holes. Follow on work could given
> options to merge or select regions that overlap, or do online rebuilds.
