HDP2.5 STORAGE ALERT

Master Collaborator

I am seeing this critical alert on HDFS application in HDP2.5 ambari dashboard as shown in picture , but when I query the hdfs on unix its showing plenty of space available 95.5G free only 5% used ?

hdfs-storage-alert.jpg

hdfs@hadoop1 ~]$ hdfs dfs -df -h
Filesystem                                    Size    Used  Available  Use%
hdfs://hadoop1.tolls.dot.state.fl.us:8020  214.8 G  11.0 G     95.5 G    5%

Re: HDP2.5 STORAGE ALERT

@Sami Ahmad from the screen shot you have attached from Ambari it is referring to the DataNode Stoage Alert which is not a HDFS storage alert. You are seeing it under HDFS alerts as DataNode is part of it. From the same screen you can see the Percent DataNodes With Available Space: affected [1]. Go to the affected datanode and clean up some space as it is utilising 94% and this is completely related to local capacity of the mount point that you have given to Datanode not related to HDFS storage.

Thanks
