Project: Kafka
Issue Type: Improvement
Reporter: Ted Yu
Quoting stack trace from KAFKA-5998 :
{code}
WARN [2018-08-22 03:17:03,745]
org.apache.kafka.streams.processor.internals.ProcessorStateManager: task [0_45]
Failed to write offset checkpoint file to /tmp/kafka-streams/<application_id>
{{ /0_45/.checkpoint: {}}}
{{ ! java.nio.file.NoSuchFileException:
/tmp/kafka-streams/<application_id>/0_45/.checkpoint.tmp}}
{{ ! at sun.nio.fs.UnixException.translateToIOException(UnixException.java:86)}}
{{ ! at sun.nio.fs.UnixException.rethrowAsIOException(UnixException.java:102)}}
{code}
When state.dir is left at default configuration, there is a chance that certain
files under the state directory are cleaned by OS.
[~mjsax] and I proposed to suggest user, through exception message, to change
the location for state.dir .
