Hi

We are generating some big model objects


> hdfs dfs -du -h /myfolder
325      975      /myfolder/__ORCHMETA__
1.7 M    5.0 M    /myfolder/model
185.3 K  555.9 K  /myfolder/predict

The issue I am facing while loading is

Error in .jcall("com/oracle/obx/df/OBXSerializer", returnSig =
"Ljava/lang/Object;",  :
  java.io.StreamCorruptedException: invalid type code: 00
Calls: orch.load.model -> <Anonymous> -> .jcall -> .jcheck -> .Call
Execution halted


As you can guess, it is from Oracle's R for Hadoop (ORAAH) product. I am
going to raise a ticket with Oracle, but thought to check here as well if
there are any solution available.
