--------------------------------
Summary: [Distributed] Prevent rebooting from damaging file
versions
Key: IOTDB-917
URL: https://issues.apache.org/jira/browse/IOTDB-917
Project: Apache IoTDB
Issue Type: Bug
Components: Core/Cluster
Reporter: Tian Jiang
During system reboots, when FileVersionController is recovered, it will
automatically increase its current version number by a small amount to prevent
the versions of new files conflict with existing files.
However, if one node in a data group reboots, its file version number will
become inconsistent with others, which causes troubles during catch-ups.
So, the maximum version number should be precisely recovered from the existing
TsFiles, so as to avoid inconsistency.
