YeonSu Han commented on TAJO-1807:
----------------------------------
I have checked this issue.
The S3 or google cloud storage is object storage. So in java stream to read a
object data must be close the output stream.
But, If create a history file every query, have too many file. Because not
close the history file in rolling time.
In org.apache.tajo.util.history.HistoryWriter:: writeQuerySummary
{code}
...
byte[] jsonBytes = ("\n" + queryInfo.toJson() +
"\n").getBytes(Bytes.UTF8_CHARSET);
try {
querySummaryWriter.out.writeInt(jsonBytes.length);
querySummaryWriter.out.write(jsonBytes);
} catch (IOException ie) {
IOUtils.cleanup(LOG, querySummaryWriter);
querySummaryWriter.out = null;
throw ie;
}
...
{code}
> Not display "Finished Queries" in query.jsp
