zhu.qing commented on FLINK-8534:
---------------------------------

And Code is attached as a BFS in graph use native flink api.

> if insert too much BucketEntry into one bucket in join of iteration will 
> cause a error (Caused : java.io.FileNotFoundException release file error)

>         Environment: windows, intellij idea, 8g ram, 4core i5 cpu, Flink 
> 1.4.0, and parallelism = 2 will cause problem and others will not.

> When insert too much entry into bucket (MutableHashTable insertBucketEntry() 
> line 1054 more than 255) will cause  spillPartition() (HashPartition line 
> 317). So 
> this.buildSideChannel = ioAccess.createBlockChannelWriter(targetChannel, 
> bufferReturnQueue); 
> And in 
> prepareNextPartition() of ReOpenableMutableHashTable (line 156)
> furtherPartitioning = true; 
> so in 
> finalizeProbePhase() in HashPartition (line 367)
>  this.probeSideChannel.close();
> //the file will be delete 
>  this.buildSideChannel.deleteChannel();
>  this.probeSideChannel.deleteChannel();
> after deleteChannel the next iteartion will fail.
>  
> And I use web-google(SNAP) as dataset.
