1) I have added serde jar file using "ADD JAR /home/hduser/softwares/hive/hive-serdes-1.0-SNAPSHOT.jar;"
2) Create table
3) The table is creates successfully
4) But when I execute any select query it throws file not found exception
hive> select count(*) from tab_tweets;
Query ID = hduser_20150604145353_51b4def4-11fb-4638-acac-77301c1c1806
Total jobs = 1
Launching Job 1 out of 1
Number of reduce tasks determined at compile time: 1
In order to change the average load for a reducer (in bytes):
set hive.exec.reducers.bytes.per.reducer=<number>
In order to limit the maximum number of reducers:
set hive.exec.reducers.max=<number>
In order to set a constant number of reducers:
set mapreduce.job.reduces=<number>

Job Submission failed with exception 'java.io.FileNotFoundException(File does not exist: hdfs://node1:9000/home/hduser/softwares/hive/hive-serdes-1.0-SNAPSHOT.jar)' FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.mr.MapRedTask
METHOD 1: Copy
hive-serdes-1.0-SNAPSHOT.jar
file from local filesystem to HDFS.METHOD 2: Change the value for
hive.aux.jars.path
inhive-site.xml
as:METHOD 3: Add
hive-serdes-1.0-SNAPSHOT.jar
in hadoop classpath. i.e., add this line inhadoop-env.sh
:Note: No need to copy the hive-serdes-1.0-SNAPSHOT.jar in to hdfs, keep it in local Fs itself.
At Query execution time. Hive will take care of it making available in all nodes as D.C
Refer this link for details : official link
FYI - refer Hive Resources
Once a resource is added to a session, Hive queries can refer to it by its name (in map/reduce/transform clauses) and the resource is available locally at execution time on the entire Hadoop cluster. Hive uses Hadoop's Distributed Cache to distribute the added resources to all the machines in the cluster at query execution time
you can add additional Jars in multipe ways:
Adding on the node from which you are running hive in .hiverc like .bashrc
cd $HOME
create a file .hiverc
cat $HOME/.hiverc
add jar /local/fs/path/to/your/file.jar // add this line
Adding jar file to hive-site.xml
hive.aux.jars.path file:///home/user/path/to/your/hive-serdes-1.0-SNAPSHOT.jar
Check jar exists at /home/hduser/softwares/hive/hive-serdes-1.0-SNAPSHOT.jar
