Hive UDF Run:Getting error in create temporary function in hive

Question

Here I have written one simple replace word UDF in java.
Then I have exported that .java file and created jar file.

Same created jar file added in hive using

Add jar jar file path ;

then I am trying to create temporary function in hive but getting below error

create temporary function  functionname as 'javaprogrampkgname.javaprogramname.';

but for this am getting below error on terminal:

FAILED: Execution Error, return code -101 from org.apache.hadoop.hive.ql.exec.FunctionTask. ReplaceUDFpkg/ReplaceUDF : Unsupported major.minor version 52.0

seems like java version mismatch. check compile and runtime java are same — Nirmal Ram, Nov 28 '16 at 09:15

Finally got the cause of this error.

Yes, this error due to java version mismatch but as:

I have written, compiled and exported as JAR in eclipse and then this exported JAR trying to use in a different version of java, here due to version mismatch the JVM could not able to call and find this JAR.

I have solved this issue by compiling my java code and creating JAR in "1.7" version which set for my Hadoop home path.

It should be the error of your different java version on the place where you created UDF and your hive java version.
