Re: Hive ORC Malformed while loading into spark data frame

Thanks much Zhan Zhang. I will open a JIRA saying orc files created using
hiveContext.sql can't be read by dataframe reader.

Hi Zang any idea why is this happening? I can load ORC files created by
Hive table but I cant load ORC files created by Spark itself. It looks like
bug.

Re: Hive ORC Malformed while loading into spark data frame

2015-09-30 Thread Umesh Kacha
Hi Zang thanks much please find the code below

Working code loading data from a path created by Hive table using hive
console outside of spark :

DataFrame df =
hiveContext.read().format("orc").load("/hdfs/path/to/hive/table/partition")

Not working code inside spark hive tables created using hiveContext.sql
insert into partition queries

DataFrame df =
hiveContext.read().format("orc").load("/hdfs/path/to/hive/table/partition/created/by/spark")

You see above is same in both cases just second code is trying to load orc
data created by Spark.

Hive ORC Malformed while loading into spark data frame

2015-09-29 Thread unk1102
Hi I have a spark job which creates hive tables in orc format with
partitions. It works well I can read data back into hive table using hive
console. But if I try further process orc files generated by Spark job by
loading into dataframe  then I get the following exception 
Caused by: java.io.IOException: Malformed ORC file
hdfs://localhost:9000/user/hive/warehouse/partorc/part_tiny.txt. Invalid
postscript.

Dataframe df = hiveContext.read().format("orc").load(to/path);  

Please guide.

Hi Zang, thanks for the response. Table is created using Spark
hiveContext.sql and data inserted into table also using hiveContext.sql.
Insert into partition table. When I try to load orc data into dataframe I
am loading particular partition data stored in path say
/user/xyz/Hive/xyz.db/sparktable/partition1=abc

How was the table is generated, by hive or by spark? 

If you generate table using have but read it by data frame, it may have some
