mapreduce异常-yarn container分配错误
部署了cdh5+hive0.12,
在hive shell执行sql,时不时会报以下错误:
FAILED:Execution error,return code 2 from org.apache.hadoop.hive.ql.exec.mr.mapredtask
检查mapreduce的stdlog,,有以下错误:
ERROR[Thead-50] org.apache.hadoop.mapreduce.v2.app.rm.RMContainerAllocator:Could not deallocate container for task attemptId attempt_1403835280145_0001_r_000000_0
从字面上看是分配container失败,请教如何解决呢
