Aihua Xu created HIVE-19204: ------------------------------- Summary: Detailed errors from some tasks are not displayed to the client because the tasks don't set exception when they fail Key: HIVE-19204 URL: https://issues.apache.org/jira/browse/HIVE-19204 Project: Hive Issue Type: Improvement Components: Query Processor Affects Versions: 3.0.0 Reporter: Aihua Xu Assignee: Aihua Xu
In TaskRunner.java, if the tasks have exception set, then the task result will have such exception set and Driver.java will get such details and display to the client. But some tasks don't set such exceptions so the client won't see such details unless you check the HS2 log. {noformat} public void runSequential() { int exitVal = -101; try { exitVal = tsk.executeTask(ss == null ? null : ss.getHiveHistory()); } catch (Throwable t) { if (tsk.getException() == null) { tsk.setException(t); } LOG.error("Error in executeTask", t); } result.setExitVal(exitVal); if (tsk.getException() != null) { result.setTaskError(tsk.getException()); } } {noformat} -- This message was sent by Atlassian JIRA (v7.6.3#76005)
