kgeisz opened a new pull request, #7230:
URL: https://github.com/apache/hbase/pull/7230

   https://issues.apache.org/jira/browse/HBASE-29507
   
   This pull request reduces the value for `DEFAULT_ROWS_IN_ITERATION` in 
IntegrationTestBackupRestore.java from 500,000 to 10,000.  The change prevents 
an OutOfMemoryError from occurring when running IntegrationTestBackupRestore 
locally. The error was discovered while testing the fix for PR #7203.  If we 
still want to use 500,000 rows for an actual integration test on a distributed 
cluster, then the row count can be overridden via the command line by using the 
`rows_in_iteration` arg (see [this 
line](https://github.com/apache/hbase/blob/master/hbase-it/src/test/java/org/apache/hadoop/hbase/IntegrationTestBackupRestore.java#L82)
 and [this 
line](https://github.com/apache/hbase/blob/master/hbase-it/src/test/java/org/apache/hadoop/hbase/IntegrationTestBackupRestore.java#L429-L431)).
