Lab is having some memory issues
hadoop fs -ls /user/
Java HotSpot™ 64-Bit Server VM warning: INFO: os::commit_memory(0x0000787a21000000, 351272960, 0) failed; error=‘Cannot allocate memory’ (errno=12)
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.
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.
Would you mind to share the steps to resolve this issue?
