using hive got exception java.lang.NoClassDefFoundError: org/apache/tez/dag/api/SessionNotRunning

Question

after configuring hadoop I could run hdfs

then install hive and edit the conf file to make it run on tez by default, but running into some special issue when using hive directly:

hive

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/tez/dag/api/SessionNotRunning

Version Info: hadoop: 2.5 hive 0.13 tez 0.41

anyone met this before?

seems not like a PATH related error.

Answer 1

My peoblem is：

Could not open connection to jdbc:hive2://localhost:10000: java.net.ConnectException: Connection refused (state=08S01,code=0)

Here is my solution and the progress to figure it out:

when run the below command to start hiveserver2

hive --service hiveserver2

the log tells the Excetion：

    Error starting HiveServer2 on attempt 1, will retry in 60000ms
java.lang.NoClassDefFoundError: org/apache/tez/dag/api/TezConfiguration

but continue to look up we find that

2018-11-16T18:45:14,836  INFO [main] server.HiveServer2: HS2 interactive HA not enabled. Starting tez sessions..
2018-11-16T18:45:14,836  INFO [main] server.HiveServer2: Starting/Reconnecting tez sessions..

so the reason is thad the default setting disable the HS2 interactive HA configuration. just chage to true to fix this in the hive-site.xml

<property>
    <name>hive.server2.active.passive.ha.enable</name>
    <value>false</value> # change false to true
</property>

Problem solved !!!

Answer 2

I temporarily solved this by add hiveconf to force hive use mr engine not tez;

like this:

hive -hiveconf hive.execution.engine=mr -e "my sql"

but as I want to use tez, anyone could help?
