Did you put a Filter on the values to remove the null? I'm trying to filter the NULL values using the Pig Filter Keyword and then use the Phoenix Pig integration to store the data. I have '\\u001' as the delimiter for multiple files. It is supported by Pig BulkLoader too.
Snippet: D = LOAD 'src_dest' using PigStorage('\\u001') as AS (IS_REPORTED:INT, PROCESSING_STATUS_ID:INT, PROGRAM_ID:INT, AFFINITY_GROUP_ID:INT); X = FILTER D BY (IS_REPORTED is not null) AND (PROCESSING_STATUS_ID is not null) AND (IS_REPORTED==1) AND (PROGRAM_ID==1) AND (PROCESSING_STATUS_ID==2) AND (AFFINITY_GROUP_ID==76); On Thu, Feb 18, 2016 at 3:06 PM, Chandeep Singh <c...@chandeep.com> wrote: > So, I added one record to your sample to match all the conditions you have > in your filter statement. > > New input: > [csingh]$ hadoop fs -cat test.txt > 1,,2,76 > 1,,,76 > ,2,,76 > 1,1,2, > 1,1,1,76 > 1,2,1,76 > > I modified the load statement to use PigStorage delimited by comma. > > D = LOAD 'test.txt' USING PigStorage(',') AS (IS_REPORTED:INT, > PROCESSING_STATUS_ID:INT, PROGRAM_ID:INT, AFFINITY_GROUP_ID:INT); > > Output: > (1,2,1,76) > > So, the NOT NULL's seem to be working. > > Pig Log’s: > > grunt> D = LOAD 'test.txt' USING PigStorage(',') AS (IS_REPORTED:INT, > PROCESSING_STATUS_ID:INT, PROGRAM_ID:INT, AFFINITY_GROUP_ID:INT); > grunt> X = FILTER D BY (IS_REPORTED is not null) AND (PROCESSING_STATUS_ID > is not null) AND (IS_REPORTED==1) AND (PROGRAM_ID==1) AND > (PROCESSING_STATUS_ID==2) AND (AFFINITY_GROUP_ID==76); > grunt> DUMP X; > 2016-02-18 23:01:06,336 [main] INFO > org.apache.pig.tools.pigstats.ScriptState - Pig features used in the > script: FILTER > 2016-02-18 23:01:06,366 [main] INFO > org.apache.pig.newplan.logical.optimizer.LogicalPlanOptimizer - > {RULES_ENABLED=[AddForEach, ColumnMapKeyPrune, > DuplicateForEachColumnRewrite, GroupByConstParallelSetter, > ImplicitSplitInserter, LimitOptimizer, LoadTypeCastInserter, MergeFilter, > MergeForEach, NewPartitionFilterOptimizer, PushDownForEachFlatten, > PushUpFilter, SplitFilter, StreamTypeCastInserter], > RULES_DISABLED=[FilterLogicExpressionSimplifier, PartitionFilterOptimizer]} > 2016-02-18 23:01:06,480 [main] INFO > org.apache.pig.backend.hadoop.executionengine.mapReduceLayer.MultiQueryOptimizer > - MR plan size before optimization: 1 > 2016-02-18 23:01:10,798 [JobControl] INFO > org.apache.hadoop.conf.Configuration.deprecation - fs.default.name is > deprecated.
