Affects Version/s: 2.4.0
Lockfiles are not being created for datanode storage directories
Key: HDFS-8469
URL: https://issues.apache.org/jira/browse/HDFS-8469
Project: Hadoop HDFS
Issue Type: Bug
Components: datanode
Affects Versions: 2.4.0
Reporter: Colin Patrick McCabe
Assignee: Colin Patrick McCabe
Attachments: HDFS-8469.001.patch
Lockfiles are not being created for datanode storage directories. Due to a
mixup, we are initializing the StorageDirectory class with shared=true (an
option which was only intended for NFS directories used to implement NameNode
HA). Setting shared=true disables lockfile generation and prints a log
message like this:
{code}
2015-05-22 11:45:16,367 INFO common.Storage (Storage.java:lock(675)) -
Locking is disabled for
/home/cmccabe/hadoop2/hadoop-hdfs-project/hadoop-hdfs/target/
test/data/dfs/data/data5/current/BP-122766180-127.0.0.1-1432320314834
{code}
Without lock files, we could accidentally spawn two datanode processes using
the same directories without realizing it.
