Ted Yu commented on HBASE-9168:
-------------------------------
A similar approach is to catch FileNotFoundException in NamespaceUpgrade.
This way existence check can be omitted.
> TestMetaMigrationConvertingToPB fails on hadoop 2.0 due to
> FileNotFoundException

>
> NamespaceUpgrade is called by TestMetaMigrationConvertingToPB
> TestMetaMigrationConvertToPB.tgz doesn't contain .archive directory.
> NamespaceUpgrade#migrateTables() calls listStatus() on .archive directory
> (hardcoded)
> Due to change of behavior in hadoop 2.0, FileNotFoundException gets thrown
> and makes the test fail.
