Jonathan Hsieh commented on HBASE-8258:
---------------------------------------
builds.apache.org's attempts [1] have been fairly flakey in general recently
for tests that are generally fail due to interference from other processes /
unit test suites.
>From an recent runs on "beefy" physical hardware, I see these test cases
>failing regularly:
{code}
org.apache.hadoop.hbase.mapreduce.TestImportExport.testSimpleCase
org.apache.hadoop.hbase.mapreduce.TestImportExport.testMetaExport
org.apache.hadoop.hbase.mapreduce.TestImportExport.testExportScannerBatching
org.apache.hadoop.hbase.mapreduce.TestImportExport.testWithFilter
org.apache.hadoop.hbase.mapreduce.TestImportExport.testWithDeletes
org.apache.hadoop.hbase.mapreduce.TestRowCounter.testRowCounterNoColumn
org.apache.hadoop.hbase.mapreduce.TestRowCounter.testRowCounterHiddenColumn
org.apache.hadoop.hbase.mapreduce.TestRowCounter.testRowCounterExclusiveColumn
{code}
TestImportExport seems flakey (50:50) while TestRowCounter seems to failed
consistently for while.
