[jira] [Updated] (DRILL-4058) NPE - we need a better error message
[ https://issues.apache.org/jira/browse/DRILL-4058?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Khurram Faraaz updated DRILL-4058:
----------------------------------
Description:
Test query returns NPE, we need a better error message. It seems to be coming from DrillBufInputStream.getStream(DrillBufInputStream.java:57)
Here is the data used in test
{code}
[root@centos-01 ~]# cat test.json
{
"c1":{"key":"value1"}
}
[root@centos-01 ~]#
{code}
Failing query that gives NPE.
{code}
0: jdbc:drill:schema=dfs.tmp> select convert_from(t,'JSON') jsn FROM `test.json` t;
Error: SYSTEM ERROR: NullPointerException
