Spark in Yarn mode gives error when installed in kerberized cluster

[#1]

Hi ,

I am using CDH 5.2 on RHEL 6.5

I am trying to install spark in yarn mode in kerberized environment.

But it fails on the 3 rd step when it tries to upload the jars after creating history server and user dir.

I was able to resolve this,

I changed a property in krb5.conf

dns_lookup_kdc=true

I was getting an error in creating KDC initial credentials.By changing this property from false to true i was able to install spark on secure kerberized with sentry cluster.

Thank you for letting us know the solution.  🙂
