[jira]TestCase in carbondata-hadoop failed

[ffpeng90]

Hi,all:
    Recently, i meet a strange problem.
    i create a table via plugin carbondata-spark and stored it on local path with table name "flightdb2". I can read it with spark, all seems to be ok.



    Then i try to use a testCase to read table "flightdb2". The testCase is CarbonInputMapperTest and it is in Module carbondata-hadoop. However this testCase will fail with error "NullPointerException".
    Case CarbonInputMapperTest.testInputFormatMapperReadAllRowsAndColumns will success when read table "testtable" which created by StoreCreator.
    All code is cloned from github and is clean, so I want to know the difference between table "flightdb2" and "testtable"?

Hi,

Please make sure the store path of "flightdb2" is given properly in side CarbonInputMapperTest class.
Please provide complete stack trace of error.

yes,  i can trace the QueryModel and see paras queryDimension and queryMeasure is the same as  spark read.
so i gusess table "flightdb2" is in the right place.
My table path is like this: ~/Documents/Intellij/carbondata/hadoop/target/store/testdb


However when loading file XXX.carbondata  in BlockIndexStore , it throw out a exception


I think everyone can have a try and reappear it. You just need a simple table created by carbon-spark.

i have update my carbon-version to 1.0.0, This problem seem to be gone.  

I will focus on carbon-hadoop API, and try something new.
