Subject [jira] [Commented] (CARBONDATA-321) Query is failing on the change of blocklet size

    **Problem:**
    If user changes the blocklet size (50) the queries will be failed.
    Currently byte size calculation in number compressor is 
    int array length * bit length=x
    bytesize= x/8+x%8;
    when cardinality is 50
    then byte size will be 3
    but to calculate the actual int array size of index reverse based on the reverse calculation
it is coming 4
    int arrayLength=(3*8)/6
    **Solution:**
    We need to round off bit length to nearest value which should be divisible by 8

    [CARBONDATA-321] If user changes the blocklet size the queries will be failed. this is
happening since the inverted index compression is not been handled properly
