EMR - Tez

Upscale/Downscale of the emr cluster corrupts hdfs jars /apps/tez/tez.tar.gz

Solution 1:

Repair the tez.tar.gz file and increase replication value

wget https://downloads.apache.org/tez/0.9.2/apache-tez-0.9.2-bin.tar.gz
tar -zxvf apache-tez-0.9.2-bin.tar.gz
hadoop fs -rm /apps/tez/tez.tar.gz
hadoop fs -copyFromLocal apache-tez-0.9.2-bin/share/tez.tar.gz /apps/tez/
hadoop fs -setrep -w 3 /apps/tez/

Solution 2:

Referring the tar file directly from S3

tez-site.xml
tez.lib.uris=s3://bucketName/tez/tez.tar.gz
