Re: global variable in spark streaming with no dependency on key
Thanks. I tried. The problem is I have to updateStatebyKey to maintain other states related to keys. Not sure where to pass this accumulator variable into updateStateBykey.

See if SparkContext.accumulator helps.

global variable in spark streaming with no dependency on key
Hi Gurus, Please help. But please don't tell me to use updateStateByKey because I need a global variable (something like the clock time) across the micro batches but not depending on key. For my case, it is not acceptable to maintain a state for each key since each key comes in different times. Yes my global variable is related to time but cannot use machine clock. Any hint? Or is this lack of global variable by design? Thanks! - To unsubscribe, e-mail: user-unsubscr...@spark.apache.org For additional commands, e-mail: user-h...@spark.apache.org
