Pascal Brueckner commented on STORM-3652:
-----------------------------------------
While the summary view now properly mentions errors again, listing the error
details within the Bolt detail view most often fails: The table just states "No
data available in table" This is not always reproducible. The error log will
sometimes be shown correctly, but in the majority of my test cases the error
log was empty.
To reproduce the issue I modified the ExclamationBolt of the storm-starter
topology to throw a RuntimeException on the first execution attempt, but
complete successfully the second time:
{{ public void execute(Tuple tuple) {}}
{{ File file = new File("/tmp/X");}}
{{ }}{{try {}}
{{ if (file.createNewFile()) {}}
{{ throw new RuntimeException(new Exception("RTEXCP"));}}
{{ }}{{}}}
{{ }}{{} catch (IOException e) {}}
{{ }}{{System.out.println("IOEXCP");}}
{{ }}}
}
Running this topology will (most of the time) show an error in the summary, but
omit the details.
