----------------------------------------------------
Summary: Pig ToDate() exception with hive partition table ,partitioned by column of DATE datatype
Key: HIVE-14282
URL: https://issues.apache.org/jira/browse/HIVE-14282
Project: Hive
Issue Type: Bug
Affects Versions: 0.15.0
Environment: PIG Version : (0.15.0)
OS Version : CentOS release 6.7 (Final)
OS Kernel : 2.6.32-573.18.1.el6.x86_64
Reporter: Raghavender Rao Guruvannagari
ToDate() function doesnt work with a partitioned table, partitioned by the column of DATE Datatype.
Below are the steps I followed to recreate the problem.
-->Sample input file to hive table :
hdfs@testhost ~$ cat test.log

--> Copied to hdfs directory:
hdfs@testhost ~$ hdfs dfs -put -f test.log /user/hdfs/
-->Create partitoned table (partitioned with date data type column) in hive:
0: jdbc:hive2://hdp2.raghav.com:10000/default> create table mytable(Dt DATE,Time STRING,Number INT,IPAddr STRING,Type STRING,Site STRING,OSType STRING,Visit INT,PhModel STRING) row format delimited fields terminated by ',' stored as textfile;
0: jdbc:hive2://testhost.com:10000/default> load data inpath '/user/hdfs/test.log' overwrite into table mytable;
0: jdbc:hive2://testhost..com:10000/default> SET hive.exec.dynamic.partition = true;
0: jdbc:hive2://testhost.com:10000/default> SET hive.exec.dynamic.partition.mode = nonstrict;
0: jdbc:hive2://testhost.com:10000/default> create table partmytable(Number INT,IPAddr STRING,Type STRING,Site STRING,OSType STRING,Visit INT,PhModel STRING) partitioned by (Dt DATE,Time STRING) row format delimited fields terminated by ',' stored as textfile;
0: jdbc:hive2://testhost.com:10000/default> insert overwrite table partmytable partition(Dt,Time) select Number,IPAddr,Type,Site,OSType,Visit,PhModel,Dt,Time from mytable;
0: jdbc:hive2://hdp2.raghav.com:10000/default> describe partmytable;
--> Try to filter with ToDate function which fails with error:
hdfs@testhost ~$ pig -useHCatalog
grunt>
grunt> temp = LOAD 'partmytable' using org.apache.hive.hcatalog.pig.HCatLoader();
grunt> temp1 = FILTER temp by dt == ToDate('2012-06-13','yyyy-MM-dd');
grunt> dump temp1;
-->Try to filter the normal table with same statement works;
grunt>
grunt> temp = LOAD 'mytable' using org.apache.hive.hcatalog.pig.HCatLoader();
grunt> temp1 = FILTER temp by dt == ToDate('2012-06-13','yyyy-MM-dd');
grunt> dump temp1;
Workaround :
Use below statement instead of direct ToDate();
grunt>temp1 = FILTER temp5 by DaysBetween(dt,(datetime)ToDate('2012-06-13', 'yyyy-MM-dd')) >=(long)0 AND DaysBetween(dt,(datetime)ToDate('2012-06-13', 'yyyy-MM-dd')) <=(long)0;
