Nikola created FLINK-16870:
------------------------------
Summary: OrcTableSource throws NullPointerException
Key: FLINK-16870
URL: https://issues.apache.org/jira/browse/FLINK-16870
Project: Flink
Issue Type: Bug
Components: Connectors / ORC
Affects Versions: 1.10.0
Environment: flink 1.10
Reporter: Nikola
Attachments: flink-1.10-minimal-example.txt,
flink-1.10-orc-exception.log
I am trying to read some ORC data from HDFS as given the example here:
[https://ci.apache.org/projects/flink/flink-docs-release-1.10/api/java/org/apache/flink/orc/OrcTableSource.html]
When I try to do this, the job crashes with NullPointerException:
{code:java}
Caused by: java.lang.NullPointerException at
org.apache.flink.orc.shim.OrcShimV200.computeProjectionMask(OrcShimV200.java:188)
at
org.apache.flink.orc.shim.OrcShimV200.createRecordReader(OrcShimV200.java:120)
{code}
I have attached a minimal version of code which can reproduce the issue. The
same piece of code (and more complex) runs fine on flink 1.8.2
I have tried to look what is causing it and it seems that the
NullPointerException happens on this line:
[https://github.com/apache/flink/blob/release-1.10/flink-formats/flink-orc/src/main/java/org/apache/flink/orc/shim/OrcShimV200.java#L188
