Hello fair internet people
I have a fully functioning 5 node Ambari cluster setup in AWS.
I am now trying to follow https://wiki.apache.org/hadoop/AmazonS3 to replace my hdfs with s3.
In my Ambari setup, I clicked on HDFS then the config tab.
In the Advanced section I found the property for
and changed it from hdfs://ip-xx-xx-xx-xx.compute.internal:8020
Then I added
with their values to the hdfs-site.xml section.
I presume this is essentially adding all these relevent values into the hdfs-site.xml config file on the server.
So, when I restart the nodes, I now get the namenode not restarting with the following error:
safemode: FileSystem s3://bucket-name is not an HDFS file system
Usage: java DFSAdmin [-safemode enter | leave | get | wait]
2014-06-30 09:56:25,604 – Retrying after 10 seconds. Reason: Execution of ‘su – hdfs -c ‘hadoop dfsadmin -safemode get’ | grep ‘Safe mode is OFF” returned 1. DEPRECATED: Use of this script to execute hdfs command is deprecated.Instead use the hdfs command for it.
Do I have to configure something else somewhere to get hdfs to like using s3? Or to get Ambari specifically to use it?
Thanks in advance
