getting issue after run the command in Hive

avatar

I am using HDP 2.4.2-258.

I ran the command on hive terminal but getting following error:-

hive> show create table hive_table;

FAILED: SemanticException Unable to fetch table hive_table. java.io.IOException: Incomplete HDFS URI, no host: hdfs://hdptest:8020:8020/

hive> show create table hive_table;

FAILED: SemanticException Unable to fetch table hive_table. java.io.IOException: Incomplete HDFS URI, no host: hdfs://hdptest:8020:8020

Dont know from where this path is taking because I updated the path with following command:-

hive --service metatool -updateLocation hdfs://hdptest1:8020 hdfs://localhost:8020

It's urgent.

Thanks in advance.

@Ashnee Sharm

You dont need to specify 8020 port when updating with metatool for updating nameservice ID

Try below command to set FS path

#hive --service metatool -updateLocation hdfs://hdptest1 hdfs://hdptest1:8020

Connect to db and verify if it has updated the location in tables SDS.

mysql> use hive;

mysql> select LOCATION from SDS;

I truncate the SDS table now getting null exception.

hive> show create table hive_table;

FAILED: SemanticException Unable to fetch table hive_table. null

Thanks for the reply issue is resolved.

I have tried this command and the command ran successfully. But still facing same issue:-

hive> select * from hive_table;

FAILED: SemanticException Unable to fetch table hive_table. java.io.IOException: Incomplete HDFS URI, no host: hdfs://hdptest1:8020:8020/

@Ashnee Sharma

Issue seems to be related to the incorrect HDFS URI at the time of table creation. Try creating new sample table and try.

The issue is with location tables are created in corrrect way. As per the comment of @rguruvannagari issue with SDS table after truncate the table that issue is resolved now getting new error:

hive> show create table hive_table;

FAILED: SemanticException Unable to fetch table hive_table. null

This issue may happen when Hive Metastore's 'DBS' table contains a location which doesn't have port.

For example, 'hdfs://sandbox-hdp.hortonworks.com/apps/hive/warehouse/dummies.db'

I think above is a valid location path, but when HS2 is restarted from Ambari, Ambari replaces not only this 'DBS' location, but also all 'SDS' locations with, for example, like below:

old location: hdfs://sandbox-hdp.hortonworks.com:8020/apps/hive/warehouse/dummies.db/emp_part_bckt/department=A new location: hdfs://sandbox-hdp.hortonworks.com:8020:8020/apps/hive/warehouse/dummies.db/emp_part_bckt/department=A

So that next time hiveserver2 is restarted, you don't see this behaviour, but you still need to correct SDS location.
