I can execute the same code from HIVE shell but from spark script i am getting this error. Is there any special Jar file i need to include. Any help will be appreciated.
I am using EMR-4.3.0, Spark 1.6.0, Hive 1.0.0.
I write a table like so (pseudocode) -
val df = <a dataframe>
df.registerTempTable("temptable")
sqlContext.setConf("hive.exec.dynamic.partition.mode","true")
sqlContext.sql("create external table exttable ( some columns ... )
partitioned by (partkey int) stored as parquet location 's3://some.bucket'")
sqlContext.sql("insert overwrite exttable partition(partkey) select columns from
temptable")
The write works fine and I can read the table back using -
sqlContext.sql("select * from exttable")
However, when I try to read the table using Hive as -
hive -e 'select * from exttable'
Hive throws a NullPointerException with the stack trace below. Any help appreciated! -

UPDATE - After messing around for a bit, it seems like null values in the data mess Hive up. How do I avoid this?
while running pig in mapreduce mode im occuring really strange error.
The pigscript.pig contains....
x= load 'hdfs://file.avro' USING AvroStorage();
some transofrmations...
fs mv src/file dest/file;
up to this point all works fine, but script continues as
y = load 'hdfs://file2.avro' USING AvroStorage();
While executed previous command i got error bellow. I double check and the file2.avro is there ... stored in the HDFS.
When I quit pig and re-run the code from the line
y = load 'hdfs://file2.avro' USING AvroStorage();
all works fine.
Any idea?

It works if sim1 was loaded from hdfs, e.g. sim1 = load 'sim' as (gid1:long, gid2:long, sim:double).
