Re: NullPointer Exception while trying to access or read ReadOnly ctx in processElement method in KeyedBroadCastProcessFunction in Apache Flink

Hi Rahul.

Could you verify that the provided code is the one that fails? Something
does not seem right for me in the stacktrace. The stacktrace shows that
you call processElement recursively, but I can not see that in the code:

com.westpac.itm.eq.pattern.TestProcess.processElement(TestProcess.java:35)
    at
com.westpac.itm.eq.pattern.TestProcess.processElement(TestProcess.java:15)
    at

Where do you exactly get the exception? When accessing the local
variable Map<String,String> incomingRule? Is it only a typo or are you
really using

Hashmap instead of java.util.HashMap? Not sure what is the Hashmap class...

If you still find some problem there, could you provide is with an
example with which we could reproduce the problem?

Best,

Dawid

Re: NullPointer Exception while trying to access or read ReadOnly ctx in processElement method in KeyedBroadCastProcessFunction in Apache Flink

Posted by Dawid Wysakowicz <dw...@apache.org>.

Could you please share with us the actual code that you are running.
Possibly without any debug statements. As I said in my first reply, I
can not rely relate the stack trace with the code you sent us. Moreover
in the code you sent us I can not see a way it could throw an Exception
at the line you annotated with: /*It's hitting nullpointer exception
when printing the size of hashmpa*/. You are accessing a local variable
in the function. It must not throw nullpointer exception (unless there
is something weird about Hashmap. Again I don't necessarily know what is
that class. It might be a typo and you meant HashMap or it is some class
that I don't know.)

Without an actual code that fails I am afraid we will not be able to
help you much. From the information I got so far I can only be guessing
you might be making wrong assumption on the order in which the
processElement and processBroadcast are called. As Kostas mentioned in
his response. There is no guarantee about the order of the two sides.

Best.,

Dawid

Re: NullPointer Exception while trying to access or read ReadOnly ctx in processElement method in KeyedBroadCastProcessFunction in Apache Flink

Posted by "bujjirahul45 ." <ra...@gmail.com>.

Hi,

Thanks for the reply incomingRule is nothing but incomingPattern it's a
typo and yes i am using in my program, here is my scenario i have streaming
of json events which need to be validated against a set of rules i have
multiple streams from which i am consuming data let say if i have Source A
and Source B my Map State has Key the sourcename and value is a map with
patternrule name as key and value is patterncondition  let say A is source
which is Key for Map State and Value is PatternName and PatternCondition
(A,(PatternName,PatternCondition)). In my use case when i have stream of
data my broadcast state have all the patterns for all the sources of data
but to make it more efficient i am trying to apply patterns of a particular
source to the stream, that's why i am trying to get patterns of a
particular source using key as source name
ctx.getBroadcastState(ruleDescriptor).get(Key); but when ever i am running
this in my local i am getting Null pointer exception when trying to access
the rules in broadcast state using key and this not consistent error
sometimes it runs and sometimes it throws null pointer exception when i ran
program in debug mode what i observed  is for successful run i see the
control is first going to processBroadcast method in
KeyedBroadcastProcessFunction and for unsuccessful run its first going to
processElement method and throwing null pointer exception above code how i
am trying to read broadcast state in processElement method i am attaching
the complete error log to the mail please help me in solving the issue i am
trying since long but nothing working for me i have even open method in
KeyedBroadcastProcessFunction where i am initiating the map state

if need any clarity please let me know below are my system details

OS: Windows 10
Java Version: 1.8
Flink Version: 1.10.0

Re: NullPointer Exception while trying to access or read ReadOnly ctx in processElement method in KeyedBroadCastProcessFunction in Apache Flink

Posted by Kostas Kloudas <kk...@gmail.com>.

Hi all,

Just as an addition to what Dawid asked, I would also like to ask:
1) which Flink version are you using? because the stack trace line
numbers do not match the current master.
2) as a clarification (although maybe not relevant here), there is no
guarantee on the order of the elements, so
the non-broadcast side may be faster and when you do

incomingPattern = ctx.getBroadcastState(ruleDescriptor).get(Key);

the "Key" may not be there yet.

Cheers,
Kostas
