Tony Reix created HDFS-6515: ------------------------------- Summary: testPageRounder (org.apache.hadoop.hdfs.server.datanode.TestFsDatasetCache) Key: HDFS-6515 URL: https://issues.apache.org/jira/browse/HDFS-6515 Project: Hadoop HDFS Issue Type: Bug Components: datanode Affects Versions: 2.4.0 Environment: Linux on PPC64 Reporter: Tony Reix Priority: Blocker
I have an issue with test : testPageRounder (org.apache.hadoop.hdfs.server.datanode.TestFsDatasetCache) on Linux/PowerPC. On Linux/Intel, test runs fine. On Linux/PowerPC, I have: testPageRounder(org.apache.hadoop.hdfs.server.datanode.TestFsDatasetCache) Time elapsed: 64.037 sec <<< ERROR! java.lang.Exception: test timed out after 60000 milliseconds Looking at details, I see that some "Failed to cache " messages appear in the traces. Only 10 on Intel, but 186 on PPC64. On PPC64, it looks like some thread is waiting for something that never happens, generating a TimeOut. I'm now using IBM JVM, however I've just checked that the issue also appears with OpenJDK. I'm now using Hadoop latest, however, the issue appeared within Hadoop 2.4.0 . I need help for understanding what the test is doing, what traces are expected, in order to understand what/where is the root cause. -- This message was sent by Atlassian JIRA (v6.2#6252)
