Tez Shuffle
Tez uses org.apache.hadoop.mapred.ShuffleHandler
provided by MapReduce
version 2.0 (MRv2) as an auxiliary service, which you can choose to configure via the
/opt/mapr/hadoop/hadoop-<version>/etc/hadoop/mapred-site.xml
file.
On a secured cluster, Tez shuffle, SSL encryption configuration is enabled in
/opt/mapr/tez/tez-<version>/conf/tez-site.xml
by default: tez.runtime.shuffle.ssl.enable |
true |
tez.runtime.shuffle.keep-alive.enabled |
true |
Also, you must configure Tez shuffle for YARN by adding the following property to the
mapred-site.xml
file. Edit the
/opt/mapr/hadoop/hadoop-<version>/etc/hadoop/mapred-site.xml
file:mapreduce.shuffle.ssl.enabled |
true |
