I have a seqence file in HDFS which has a custom writable as value.
When i am trying to access this file in hive , i created a deserializer ,build a jar for it and added that jar through hive .
hive>add jar jar_name;
Then i am able to query that sequence file through hive.
Now How do i achieve the same through tableau?
Does it have the possibility of adding the jar to its classpath or is there anr other approach?
Please help me at the earliest.
You can use the 'Initial SQL' option to specify the same 'ADD JAR...' command. See the following page for more details: Extra Capabilities for Hadoop Hive | Tableau Software
Note that this does not yet work for Cloudera Impala since its initial release does not support UDFs or UDAFs.
