Jason Vas Dias commented on HBASE-9965:
---------------------------------------
I think this happens because the global 'fsShutdownHooks' object has a null
value:
org.apache.hadoop.hbase.regionserver.ShutdownHook.suppressHdfsShutdownHook(ShutdownHook.java:196):
if (!fsShutdownHooks.containsKey(hdfsClientFinalizer) &&
!ShutdownHookManager.deleteShutdownHook(hdfsClientFinalizer)) {
throw new RuntimeException("Failed suppression of fs shutdown hook: " +
hdfsClientFinalizer);
}
Running the base master with the java debugger, 'jdb', and stopping in
suppressHdfsShutdownHook , shows that
'fsShutdownHooks' is an undefined symbol and has a null value.
The code should be checking if the fsShutdownHooks object is null before it is
accessed, and should return if so.
I've now checked out the hbase SVN and will try building with the suggested
change, testing, & will report back.
