multi way equi join query hangs on rpm version based on 29th. Explain plan does not return
anything, web UI shows query as PENDING state. Test was run on 4 node cluster on CentOS. There
are no errors/exceptions reported in drillbit.log

Hanging query is,

{code}
0: jdbc:drill:> select bi.columns[0], ci.columns[0], di.columns[0], fi.columns[0], ini.columns[0],
vi.columns[0]
. . . . . . . > from `bgint_f.csv` bi,
. . . . . . . > `char_f.csv` ci,
. . . . . . . > `dbl_f.csv` di,
. . . . . . . > `float_f.csv` fi,
. . . . . . . > `int_f.csv` ini,
. . . . . . . > `vchar_f.csv` vi
. . . . . . . > where bi.columns[0] = ci.columns[0]
. . . . . . . > and di.columns[0] = fi.columns[0]
. . . . . . . > and ini.columns[0] = vi.columns[0]
. . . . . . . > and ci.columns[0] = di.columns[0]
. . . . . . . > and fi.columns[0] = ini.columns[0]
. . . . . . . > and ci.columns[0] = ini.columns[0];
{code}
