Todd Lipcon created HDFS-3800: --------------------------------- Summary: QJM: improvements to QJM fault testing Key: HDFS-3800 URL: https://issues.apache.org/jira/browse/HDFS-3800 Project: Hadoop HDFS Issue Type: Sub-task Affects Versions: QuorumJournalManager (HDFS-3077) Reporter: Todd Lipcon Assignee: Todd Lipcon
This JIRA improves TestQJMWithFaults as follows: - the current implementation didn't properly unwrap exceptions thrown by the reflection-based injection method. This caused some issues in the code where the injecting proxy didn't act quite like the original object. - the current implementation incorrectly assumed that the recovery process would recover to _exactly_ the last acked sequence number. In fact, it may recover to that transaction _or any greater transaction_. It also adds a new randomized test which uncovered a number of other bugs. I will defer to the included javadoc for a description of this test. -- This message is automatically generated by JIRA.
