Hive HBase snapshot query results in exception

NitinA — Fri, 16 Sep 2022 09:39:24 GMT

Hi, we are using CDH5.4.4 and I am trying to use Hive to query HBase snapshots. But when I issue a query I am getting the following exception in the hive CLI

Failed with exception java.io.IOException:java.io.IOException: java.lang.NoClassDefFoundError: com/yammer/metrics/core/MetricsRegistry

Here are the steps I took

1. Created an HBase snapshot 'snapshot_20150827'

2. In Hive CLI executed the following

a. Create external table

CREATE EXTERNAL TABLE e(id STRING,.....) STORED BY 'org.apache.hadoop.hive.hbase.HBaseStorageHandler'
WITH SERDEPROPERTIES ("hbase.columns.mapping" = ":key,....")

TBLPROPERTIES ("hbase.table.name" = "e", "hbase.table.default.storage.type" = "binary")

b. SET hive.hbase.snapshot.name=snapshot_20150827;

c. Execute the query

select * from e where id = '...';

and this gives me the exception noted above, please help.

The snapshot read path uses a few more jars than the default table read path code does, and the error suggests that at least one such extra jar is not on the default set of aux-jars pre-added for Hive-HBase integration in CDH.

You will need to do an "ADD JAR /opt/cloudera/parcels/CDH/lib/hbase/lib/metrics-core-2.2.0.jar;" to get this required class on the Hive CLI classpath.

Thanks for the reply Harsh. But that did not help. I tried ADD JAR but still getting the same error. Here is what I see from hive shell

hive> ADD JAR /opt/cloudera/parcels/CDH/lib/hbase/lib/metrics-core-2.2.0.jar;
Added [/opt/cloudera/parcels/CDH/lib/hbase/lib/metrics-core-2.2.0.jar] to class path
Added resources: [/opt/cloudera/parcels/CDH/lib/hbase/lib/metrics-core-2.2.0.jar]
hive> SET hive.hbase.snapshot.name=snapshot_20150920
> ;
hive> select * from e where id = '...';
OK
Failed with exception java.io.IOException:java.io.IOException: java.lang.NoClassDefFoundError: com/yammer/metrics/core/MetricsRegistry

I should add that the jar file does exist at the location in ADD JAR

$ ls -ltr /opt/cloudera/parcels/CDH/lib/hbase/lib/metrics-core-2.2.0.jar
lrwxrwxrwx 1 root root 36 Aug 13 14:40 /opt/cloudera/parcels/CDH/lib/hbase/lib/metrics-core-2.2.0.jar -> ../../../jars/metrics-core-2.2.0.jar

Looks like the jar is also required on the front-end. In addition to the
ADD JAR within the prompt, please also launch the CLI instead in this way:

~> export HADOOP_CLASSPATH=$(hbase classpath)
~> hive

No go yet Harsh, same error again. Here is what I did.

$ export HADOOP_CLASSPATH=$(hbase classpath)
$ sudo -u hdfs hive

I did verify that $(hbase classpath) has the metrics-core-2.2.0.jar.

The use of sudo will not pass forward your local environment. Login and try
instead.

Thanks Harsh, that was it. It works!

We too have the similar issue while reading from the hbase snapshot . Here is our senario
Created a table in HBASE (create 'TEST_HBASE_TABLE','cf')
Created a hive external hbase table with name TEST_EXTERNAL_HBASE_TABLE
created snapshot for (snapshot 'TEST_HBASE_TABLE','TEST_SNAPSHOT')
set the hive hbase property (set hive.hbase.snapshot.name=TEST_SNAPSHOT)
execute the query ( select * from TEST_EXTERNAL_HBASE_TABLE )

got the below exception . Need some help in fixing this issue
