--------------------------------------
Summary: ViewFileSystem should init mount points lazily
Key: HADOOP-11557
URL: https://issues.apache.org/jira/browse/HADOOP-11557
Project: Hadoop Common
Issue Type: Improvement
Components: viewfs
Affects Versions: 2.6.0
Reporter: Gera Shegalov
Assignee: Gera Shegalov
ViewFs initialization overhead can range from a couple to 10+ seconds linearly
increasing with the number of mounted namespaces. Eager initialization is both
expensive (especially when multiplied by MR tasks if viewfs is the defaultFS)
and also provides for frustrating experience for users interactively working
via FsShell with a single mount point (MP) under their user directory. Internal
directories should not require MP initialization at all.
