Fixed Issues in HBase
Review the list of Apache HBase issues that are resolved in Cloudera Runtime 7.2.11.
- CDPD-28309: This change is trying to make the check of table existence backward compatible with hbase-1.x such that CldrCopyTable of HBase-2.x communicates with a HBase-1.x cluster.
- Detail: in `checkOutputSpecs` when checking table existence with using connection to check with hbase:meta, it fails when we're communicating with different hbase versions, e.g. using hbase-2.x client checking with hbase-1.x cluster that a column `family` does not exist in hbase-1.x's hbase:meta. This issue is resolved.
