I am having the same issue, not able to run HDFS commands or launch pyspark and spark.

I am also not able to access any Hive/Pig commands. Any luck ?

same issue here… Ambari is also down

Ambari is down, any one monitoring the cluster.

@kvlprasad123 @saranvisa Issue is fixed. Ambari is working fine.

Thx, can I use spark 2.0 as it is saying 4040 has been used by some other version, ant work around.

@kvlprasad Yes you can use spark 2 also by specifying spark major version as 2.

@BaLu_SaI Thankyou!
