Tez job fails with ‘vertex failure’ error

When you run your hive job on tez execution engine then you may see job failure due to ‘vertex failure’ error. Or you may see following error in your logs.

This error is because Tez containers are not allocating enough memory to run the query.

Resolution: So now to solve this issue you have to increase memory for resources with adjusting following parameters .

tez.am.resource.memory.mb=4096 
tez.am.java.opts=-server -Xmx3276m -Djava.net.preferIPv4Stack=true -XX:+UseNUMA -XX:+UseParallelGC 
hive.tez.container.size=4096 
hive.tez.java.opts=-server -Xmx3276m -Djava.net.preferIPv4Stack=true -XX:+UseNUMA -XX:+UseParallelGC
