Hi All, I am facing the below issue while creating an dir on HDFS with Minio S3 as storage backend - com.amazonaws.AmazonClientException: Unable to verify integrity of data upload. Client calculated content hash (contentMD5: 1B2M2Y8AsgTpgAmY7PhCfg== in base 64) didn't match hash (etag: null in hex) calculated by Amazon S3. You may need to delete the data stored in Amazon S3.

I had the same issue which was due to mixed case of hostname. I ensured that the hostname is uniform(lower case) and restarted the server. This fixed the issue.

Did you try HDFS Service check? Is it successful?

Can you please share the REST API Command which you are using to fetch the groups?

@Jobin George This is real cool. I have tried to build a similar functionality tool using Flink as my Stream Processor. I call it Applerts :).

Can we add an existing KNOX Service to Ambari?

How to add/manage multiple KNOX Gateways in Ambari?

hemant_dindi · ‎03-18-2016

Thanks @Predrag. It worked when I changed it through Ambari.

I have modified the statement at line 66 in the file oozie-env.sh export OOZIE_CLIENT_OPTS="${OOZIE_CLIENT_OPTS} -Doozie.connection.retry.count=2 to export OOZIE_CLIENT_OPTS="${OOZIE_CLIENT_OPTS} -Doozie.connection.retry.count=2" We are getting the same error. What could be the possible value for OOZIE_CLIENTS_OPTS in HDP 2.4? Thanks.
