Issue while connecting to HDFS
Posted: Fri Sep 30, 2016 11:53 am
Hi,
I am getting below errors while trying to connect to HDFS through datastage using any stage like BDFS,HDFS File connector, File Connector.
Error 1:
main_program: Fatal Error: Failed to read data from Application Master sending YARN resource information. Check the health of YARN/Hadoop. Socket error: Connection reset by peer. Look into YARN Client's logs for more information at /opt/IBM/InformationServer/Server/PXEngine/logs/yarn_logs/yarn_client.root.out*
Error2:
Fatal Error: Failed to read data from Application Master on allocated containers. Try reducing APT_YARN_CONTAINER_SIZE if the YARN cluster is running low on resources. Also check that yarn.scheduler.minimum-allocation-mb setting in yarn-site.xml is set below APT_YARN_CONTAINER_SIZE. If yarn.nodemanager.vmem-check-enabled=true check if the virtual memory size for containers needs to be increased.. Socket returned end of file. Look into Application Master's logs for more information at mildatastage:/usr/local/hadoop-2.7.2/logs/userlogs/application_1475245442231_2781/container_1475245442231_2781_01_000001/../pxyarn_logs/oshjob.2781_0. These logs will be moved to a log aggregation directory after job completion if Hadoop log aggregation is enabled.
Error3:
main_program: Waiting for YARN containers with the section leader processes to start running.
main_program: Accept timed out retries = 39
"
"
main_program: **** PX on Hadoop startup failed ****
main_program: The TCP port being used for startup is 10,002; the associated socket number is 9.
main_program: Unable to contact one or more Section Leaders.
Probable configuration problem; contact Orchestrate system administrator.
Can any one please help me out in this.
Thanks in advance
