[FLINK-2500][Streaming]remove a unwanted "if" branch
This "if" is pointless since the "for" will do the same check.
And add a new temporary var(int size) so that
âdataStream.unionedStreams.size()â will just be called once.
Instead "dataStream.unionedStreams.size()" will be called every time when
"i++" and it do harm to the performance.
