----------------------------------
Hi Fabian,
Thanks for your explanation, if I understood correctly. The goal of the
supposed test is to verify the inputFormat's methods are called in correct
order during the life circle of a DataSet. For example (in pseudo code)
{quote}
...
HadoopInputFormat h = new HadoopInputFormat(WrappedFormat, k, v, Job)
DataSet d= env.createInput(h)
d.collect()
...
{quote}
During this flink task, the test code verify the order of the following events
for WrappedFormat.
bq.
configure()->getSplits()->reflection-construction->configure()->getRecordReader()
And also for WrappedInputSplits, there is a similar checking for orders of the
WrappedInputSplits's methods. Is this correct?
I'd like to work on this issue as a process to getting familiar with the flink
code base. But since this is a major issue, please don't assign me to the issue
so that we don't prevent other people with more knowledge of it from resolving
it in a more timely manner .
Thanks!
