Default location for spark event log history is hdfs:///spark-history (Spark) and hdfs:///spark2-history/ (spark2).

This will help to debug spark-history page load issue or if you have huge count of event log files you can archive it by creating the new active location.

Following are the steps to change this default location.

1. Create new directory on hdfs for e.g

$hdfs dfs -mkdir /spark2-history_new 
$hdfs dfs -chown spark:hadoop /spark2-history_new

2. Login to Amabri==>Spark==>config.

3. Update following parameters with new path "hdfs:///spark2-history_new/ " as follow.
