             Summary: NPE from CTAS partitioned by a projected casted null
                 Key: DRILL-4872
                 URL: https://issues.apache.org/jira/browse/DRILL-4872
             Project: Apache Drill
          Issue Type: Bug
          Components: Functions - Drill
    Affects Versions: 1.7.0
            Reporter: Boaz Ben-Zvi
             Fix For: Future


Extracted from DRILL-3898 : Running the same test case on a smaller table ( store_sales.dat from TPCDS SF 1) has no space issues, but there is a Null Pointer Exception from the projection:

Caused by: java.lang.NullPointerException: null
	at org.apache.drill.exec.expr.fn.impl.ByteFunctionHelpers.compare(ByteFunctionHelpers.java:100) ~[vector-1.8.0-SNAPSHOT.jar:1.8.0-SNAPSHOT]
	at org.apache.drill.exec.test.generated.ProjectorGen1.doEval(ProjectorTemplate.java:49) ~[na:na]
	at org.apache.drill.exec.test.generated.ProjectorGen1.projectRecords(ProjectorTemplate.java:62) ~[na:na]
	at org.apache.drill.exec.physical.impl.project.ProjectRecordBatch.doWork(ProjectRecordBatch.java:199) ~[drill-java-exec-1.8.0-SNAPSHOT.jar:1.8.0-SNAPSHOT]

A simplified version of the test case:

0: jdbc:drill:zk=local> create table dfs.tmp.ttt partition by (x) as select case when columns[8] = '' then cast(null as varchar(10)) else cast(columns[8] as varchar(10)) end as x FROM dfs.`/Users/boazben-zvi/data/store_sales/store_sales.dat`;
Error: SYSTEM ERROR: NullPointerException
