Whenever I am running a hive query - select * from table. It is running fine. But when i m trying to run a MR job for query - select count(*) from table. It is failing with the following error -
Total MapReduce jobs = 1

I could not find a way around this problem. I also looked into this question
But could not find a way around Integer.MAX_VALUE. I would really appreciate any suggestion.
We are using Cloudera 5.6. We have configured Sentry for Hive. Whenever we issue an insert statment, it fails with the below exception. But when we check the table, the row is inserted properly. We have set all the permissions to hive.

I have noticed this issue when you try altering table with format/syntax along with database name. I.e something like : "<DATABASE>.<TABLENAME>".. Somehow this looks like an issue.
In order to overcome it, explicitly mention the database before you execute the actual query. A sample illustration :
use sampledb;
alter employeeTable .... ; // This works
vs
[Do not use the below]
alter sampledb.employeeTable.... // This doesn't work

Thanks.
The first error is not relevant and does not affect Hive querying, as you have seen.
Regarding the second error, most probably it is because the stored data in HDFS is in Json format (most probably stored by the Cygnus tool) and a Json SerializerDeserializer (serde) must be set. You can do this by executoing the following sentence before doing the select column from table:
$ add jar /usr/local/apache-hive-0.13.0-bin/lib/json-serde-1.3.1-SNAPSHOT-jar-with-dependencies.jar;
$ select column from table;

Cassandra 1.2.6
Im able to create EXTERNAL table with the following HIVE Query
CREATE EXTERNAL TABLE input(number string,name string,address string) STORED BY 'org.apache.hadoop.hive.cassandra.cql.CqlStorageHandler' WITH SERDEPROPERTIES ("cassandra.columns.mapping" = ":key, name, address", "cassandra.ks.name" ="cassandradb", "cassandra.host" = "localhost" ,"cassandra.port" = "9160") TBLPROPERTIES ("cassandra.input.split.size" = "64000","cassandra.range.size" = "1000","cassandra.slice.predicate.size" = "1000");
(The table "input" is already existing and containing some data in cassandra created with CQL3)
However, When I try to read data with the following query
select * from input where number="1";
Im facing the folowing issue:
Total MapReduce jobs = 1
Launching Job 1 out of 1
Number of reduce tasks is set to 0 since there's no reduce operator
java.io.IOException: Could not get input splits
