------------------------------------------
Summary: DataNode Data Directories Which Contain Meta Information
Tags Trigger Alerts
Key: AMBARI-13880
URL: https://issues.apache.org/jira/browse/AMBARI-13880
Project: Ambari
Issue Type: Bug
Components: ambari-agent, ambari-server
Affects Versions: 2.1.2
Reporter: Vitaly Brodetskyi
Assignee: Vitaly Brodetskyi
Priority: Critical
Fix For: 2.1.3
HDFS allows the ability to tag DataNode data directories with meta information:
https://hadoop.apache.org/docs/stable/hadoop-project-dist/hadoop-hdfs/ArchivalStorage.html
Which results in paths that look like:
[DISK]/hadoop/hdfs/data,[SSD]/hadoop/hdfs/ssd
Many of our scripts assume that directories specified in
hdfs-site/dfs.datanode.data.dir are actual paths and perform operations like
os.path.isdir which will fail with meta data.
