Authentication issue in storm with zookeeper

HariprasathAS — Fri, 19 Apr 2024 08:52:36 GMT

I am trying to setup apache-storm in HPE Ezmeral Data Fabric 7.3 by installing it manually since it is discontinued(https://docs.ezmeral.hpe.com/datafabric-customer-managed/75/InteropMatrix/r_discontinued_eco_components.html).

To start the storm service, zookeeper service is needed. When we start the storm service, it failed to authenticate with zookeeper since zookeeper is configured with MAPR-SECURITY mechanism.

java.lang.Error: org.apache.storm.shade.org.apache.zookeeper.KeeperException$AuthFailedException: KeeperErrorCode = AuthFailed for /storm

I tried various authentication properties in storm configuration file, but it didn't work. I have referred older Storm documentation of Ezmeral(https://docs.ezmeral.hpe.com/datafabric-customer-managed/52/Storm/Storm_ConfigBasic.html) and found that it is using Kerberos authentication. But my EDF 7.3 is using MAPR_SECURITY as default authentication mechanism.

So, just wanted to know whether we can connect storm with zookeeper having MAPR-SECURITY authentication mechanism.

Hello HariprasathAS,

Thank you for reaching out to our community.

As you mentioned, Apache Storm is in a discontinued state. I suspect that the version of Storm you installed does not come from a currently available package repository on https://package.ezmeral.hpe.com/.

MapR-SASL is an originally implemented authentication mechanism, and there are code-level differences between the EEP version and the open-source version. As a result, MapR-SASL is not supported in EDF-7.3.

If you haven't already, you can try configuring these Java security settings as described in the article "Using Java Applications with Secure Clusters" to see if it resolves the issue.
