@sivareddy akkala

Please check the Falcon logs because it is 503 (Internal Server Error), means Falcon is having some internal server issues.

Check in the logs if you find any ERROR and please share the same.

Also please check the following directory permissions and ownership is correct?

[root@sandbox ~]#  ls -ld /hadoop
drwxr-xr-x 10 root root 110 Apr  6 07:16 /hadoop

[root@sandbox ~]# ls -ld /hadoop/falcon/
drwxr-xr-x 5 falcon root 46 Sep 15  2016 /hadoop/falcon/

[root@sandbox ~]# ls -ld /hadoop/falcon/data
drwxr-xr-x 3 root root 20 Sep 15  2016 /hadoop/falcon/data

[root@sandbox ~]# ls -ld /hadoop/falcon/data/lineage/
drwxrwxr-x 3 falcon hadoop 20 Sep 15  2016 /hadoop/falcon/data/lineage/

[root@sandbox ~]# ls -ld /hadoop/falcon/data/lineage/graphdb/
