methods I've tried (but no resolution): 1. ambari-server restart && ambari-agent restart 2. pip install python-requests==2.6+ (already on supported version) 3. ./start_hdfs_topology.sh - fails with the same stderr/stdout as when run on ambari-webui
errors encounted are below: stderr: https://pastebin.com/kD76tBM4 stdout: https://pastebin.com/Q1GLNNZL A similar issue is in the Hortonworks community page: https://community.hortonworks.com/questions/228103/problem-in-starting-metron-indexing-metron-indexin.html Environment: [MASTER] Centos7 - x86_64 16GB RAM 120 GB Disk - test 8x CPU master_components: https://pastebin.com/HaB48nB2 [NODE] Centos7 - x86_64 4GB RAM 120 GB Disk - test 4x CPU node_components: https://pastebin.com/BhpvgqWJ
