Date Wed, 21 May 2014 11:59:38 GMT
Liu Shaohui created HBASE-11223:
-----------------------------------

             Summary: Limit the actions number of a call in the batch 
                 Key: HBASE-11223
                 URL: https://issues.apache.org/jira/browse/HBASE-11223
             Project: HBase
          Issue Type: Bug
          Components: Client
    Affects Versions: 0.99.0
            Reporter: Liu Shaohui
            Assignee: Liu Shaohui


Huge batch operation will make regionserver crash for GC.
The extreme code like this:
{code}
    final List<Delete> deletes = new ArrayList<Delete>();
    final long rows = 4000000;
    for (long i = 0; i < rows; ++i) {
      deletes.add(new Delete(Bytes.toBytes(i)));
    }
    table.delete(deletes);
{code}
We should limit the actions number of a call in the batch.
