Description

Got this test failure:
REGRESSION: org.apache.hadoop.hbase.client.TestMetaScanner.testConcurrentMetaScannerAndCatalogJanitor

Error Message:

Issue Links

• is duplicated by: HBASE-8590 [0.94] BlockingMetaScannerVisitor should check for parent meta entry while waiting for split daughter
• relates to: HBASE-8505 References to split daughters should not be deleted separately from parent META entry
