Re: does spark really support label expr like && or || ?

[Chang Ya-Hsuan]

are you trying to do dataframe boolean expression?
please use '&' for 'and', '|' for 'or', '~' for 'not' when building
DataFrame boolean expressions.

example:

>>> df = sqlContext.range(10)
>>> df.where( (df.id==1) | ~(df.id==1))
DataFrame[id: bigint]
