I try this but get errors ( what is wrong in my syntax ? ) , ( master02 is the name of park-history server )

.

curl -sH "X-Requested-By: ambari" -u admin:admin -i curl http://master02:8080/api/v1/applications

.

@Michael Bronson,

I see that you are using port 8080.

For spark history server port is 18080 by default

for spark2 history server port is 18081 by default. You can check the port in UI where you saw the applications

ok , now I am using this:

.

curl -sH "X-Requested-By: ambari" -u "$API_USER"":""$API_PASSWORD" -i curl http://master02:18081/api/v1/applications

.

but no any output from command

what its wrong ?

Run this command as is. No need to append headers and password. In above command you were using curl twice.

curl http://master02:18081/api/v1/applications | grep "\"id\"" > a.txt

Hi, if there are more no of files are present in spark history Server, then FS would not be working as expected. In that case, We may need to write a script to delete the old files that are more then 7 days ( or as per your requirement) from the Spark history server location . Thanks Arun
