Jiuming Huang created HBASE-7102: ------------------------------------ Summary: The process of disappear without any exception Key: HBASE-7102 URL: https://issues.apache.org/jira/browse/HBASE-7102 Project: HBase Issue Type: Bug Components: regionserver Affects Versions: 0.94.2 Environment: My HBase culster contains 7 computers. One is the master and zookeeper server, the other 6 are the region servers.
The operatiing system is Centos 5.6 with kenerl 2.6.18-238.el5. The jdk version is 1.7.0_03 Reporter: Jiuming Huang The culster is started normally. It can work when the I/O pressure is small. However, when I run a large pressure job (with a lot of threads, each of which writes and reads frequently) about one hour, one of the region server will crash. I investigated the logs of the HRegionServer, they didn't contain any exception log. Specifically, the log of the down server ends with some normal log (info level log). This bug can be replayed easily, and each time the crashed server is different. Even more, the log of the crashed server ends with different information for different experiment. I really don't know why the process of HRegionServer disappear so weirdly. If the process is crashed due to my configuration or the enviornment, the log should contain some exception information, right? So, I doubt the reason is the JVM crashed. But I didn't find any error log in JVM. How to go on the test to find the reason? -- This message is automatically generated by JIRA.
