Akira AJISAKA commented on HDFS-5562:
-------------------------------------
Thanks for your comment!
bq. java.lang.RuntimeException: Cannot start datanode because the configured
max locked memory size (dfs.datanode.max.locked.memory) is greater than zero
and native code is not available.
The Exception occurred because max locked memory size is set to 16384 by line
698 of TestCacheDirectives.java.
{code}
conf.setLong(DFS_DATANODE_MAX_LOCKED_MEMORY_KEY, CACHE_CAPACITY);
{code}
IMO, the tests are to be skipped If native code is not available.
