@cloud-fan please do not backport this to 2.2. In 2.2 we don't have
SPARK-18016 and this is adding new variables in the case of coalesce. Thus it
can generate an higher pressure on the constant pool and this may even cause a
regression IMHO.--- --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
