-----------------------------------------
Summary: OIV parsing tool throws NPE for a FSImage with multiple
InodeSections
Key: HDFS-16077
URL: https://issues.apache.org/jira/browse/HDFS-16077
Project: Hadoop HDFS
Issue Type: Bug
Reporter: Ravuri Sushma sree
Assignee: Renukaprasad C
An FSImage with Multiple InodeSections is resulting in NPE when accessed
through OIV Tool with default Parser (WEB)
This issue is reproducible only with multiple InodeSections (Writing more than
1 Million Files)
On analyzing the code further we found that NPE is caused in
org.apache.hadoop.hdfs.tools.offlineImageViewer.FSImageLoader.fromINodeId(long).
fromINodeId(long) is searching for Inode in an Inodesection which doesn't have
the Inode(but exists in another InodeSection)
