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?
