Add error message when failed to infer version #63

Closed sadikovi closed 7 years ago

sadikovi commented 7 years ago

This PR adds error message for situation when version inference fails, e.g. when reading from folder with corrupt NetFlow files, or non-NetFlow files. Now it will show error like this:

java.io.IOException: Failed to infer version for provided NetFlow files using path 
'file:/spark-netflow/temp/attribute.spark', reason: java.io.IOException: Corrupt 
NetFlow file. Wrong magic number. Try specifying version manually using 'version' option

Caused by: java.io.IOException: Corrupt NetFlow file. Wrong magic number
  at com.github.sadikovi.netflowlib.NetFlowReader.<init>(NetFlowReader.java:137)
  at com.github.sadikovi.netflowlib.NetFlowReader.prepareReader(NetFlowReader.java:80)

Closes #62.
