------------------------------
Summary: TestJournalNode#testJournal fails because of test case
execution order
Key: HDFS-4004
URL: https://issues.apache.org/jira/browse/HDFS-4004
Project: Hadoop HDFS
Issue Type: Bug
Components: ha
Reporter: Chao Shi
Priority: Minor
Fix For: QuorumJournalManager (HDFS-3077)
I'm running HDFS test on HDFS-3077 branch. I found TestJournalNode#testJournal
fails sometimes. The assertion failed is:
MetricsAsserts.assertCounter("BatchesWritten", 0L, metrics);
The reason is when testHttpServer is running before testJournal, it will write
some logs to JN. The fix is simple: assign a new JID for each test case, so
that they will use different metrics.
