hadoop - Apache Spark accessing the data in hdfs through cross cluster -

-

i running spark on amazon emr public dns is, lets say, 23.21.40.15.

now executing spark jar on cluster & want write output of spark job other amazon emr hdfs public dns 29.45.56.72.

i able access own cluster hdfs i.e. 23.21.40.15 not able write cluster 29.45.56.72.

  • what need spark job can access cross cluster hdfs??
  • if possible, can share sample code this??

when set output dir in spark job can set credentials access this:

hdfs://username:password@hostname:port/pathtofolder

pd: shouldn't write ips of cluster in public question ;)
