James Clampffer updated HDFS-10952: ----------------------------------- Parent Issue: HDFS-14032 (was: HDFS-8707) > libhdfs++: Fix test_libhdfs_threaded_hdfspp_test_shim_static > non-deterministic failures > --------------------------------------------------------------------------------------- > > Key: HDFS-10952 > URL: https://issues.apache.org/jira/browse/HDFS-10952 > Project: Hadoop HDFS > Issue Type: Sub-task > Components: hdfs-client > Reporter: James Clampffer > Assignee: James Clampffer > Priority: Major > > test_libhdfs_threaded_hdfspp_test_shim_static has started failing more often > and not a whole lot has changed that should directly impact this. > It looks like the failure mode is error injection in the read pipeline. > Until HDFS-10951 is completed reads don't have a retry mechanism so any error > injection will cause that read to fail. However that doesn't explain why > these failures have been happening more frequently lately. The failures seem > to be hardware or timing specific; they almost never happen in some > environments and happen fairly frequently in others. It might help to set up > a test harness to step through revisions and see if a specific commit causes > the probability of a failure to go up. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
