-----------------------------
Summary: Too long namespace/table/column name cause
CreateTableProcedure stuck
Key: HBASE-28091
URL: https://issues.apache.org/jira/browse/HBASE-28091
Project: HBase
Issue Type: Bug
Components: proc-v2
Affects Versions: 2.4.13
Environment: Centos 7
HBase 2.4.13
Reporter: guluo
Too long namespace/table/column name cause CreateTableProcedure stuck
Due to the limitations of DFSConfigKeys.DFS_NAMENODE_MAX_COMPONENT_LENGTH_KEY,
we cannot create directory if the the length of compoent exceeds this value.
1. Too long table name cause CreateTableProcedure is Running always and it
would not end
2. We can create namespace if namespace is too long, however we will encounter
the same problem as situation 1 if we create table with this namespace
3. we will also encounter the same problem as situation 1 if we create table
with long column family name. Although HBase requires that the length of column
family cannot exceed the Byte.MAX_VALUE, We may still fail if we set the value
of DFSConfigKeys.DFS_NAMENODE_MAX_COMPONENT_LENGTH_KEY to be less than
Byte.MAX_VALUE
