A spilling test when run on test build with hdfs erasure coding turned on hits an out of memory error on the hdfs scan node. This happens because the test is tuned for a regular 3 node minicluster without hdfs erasure coding. Fix is to simply increase the memory limit on the test to accommodate this difference yet keep it small enough to achieve desired spilling on the hash join node. Testing: Ran it on an EC enabled minicluster to make sure it works Change-Id: I207569822ba7388e78936d25e2311fa09c7a1b9a Reviewed-on: http://gerrit.cloudera.org:8080/11740 Reviewed-by: Impala Public Jenkins <impala-public-jenkins@cloudera.com> Tested-by: Impala Public Jenkins <impala-public-jenkins@cloudera.com>
