IndexOutOfBoundsException when trying to read big file (gaming_data1.csv)
Gergely Novák created BEAM-2110:
-----------------------------------
Summary: HDFSFileSource throws IndexOutOfBoundsException when trying to read big file (gaming_data1.csv)
Key: BEAM-2110
URL: https://issues.apache.org/jira/browse/BEAM-2110
Project: Beam
Issue Type: Bug
Components: sdk-java-core
Environment: CentOS 7, Oracle JDK 8
Reporter: Gergely Novák
Assignee: Davor Bonaci
I modified the wordcount example to read from HDFS with this code:
{code}
pipeline.apply(Read.from(HDFSFileSource.fromText(options.getInput())))
{code}
This worked for a number of small files I tried with. But with the included example: gs://apache-beam-samples/game/gaming_data*.csv (moved to HDFS) fails with the following trace:
