Yiqun Lin commented on HDFS-13245:
----------------------------------
Thanks [~yiran] for updating the patch. Some comments from me:
*StateStoreSQLImpl .java*
1.In method {{insertRecord}} and {{updateRecord}},
{code}
} catch (UnsupportedEncodingException e) {
+ LOG.error("Cannot insert record for \"{}\", sql: \"{}\".",
+ tableName, sql, e);
+ } finally {
{code}
'Cannot insert record for' can be updated to ''Unsupported encoding error for'
2.
{code}
LOG.error("Cannot auto create table \"{}\"" +
+ ". type is \"{}\", sql: \"{}\".", dbType, tableName, sql, e);
{code}
{{. type}} should be {{, type}}
*hdfs-rbf-default.xml.java*
1. In description of {{dfs.federation.router.store.sql.jdbc.class}}, we miss
the JDBC class for HSSQLDB.
2.'Database connection url. such as' updates to {{Database connection url, such
as}}
3.'if value less than 1, use 1.' updates to {{If value less than 1, use 1.}}
4. For the setting
{{dfs.federation.router.store.sql.auto.create.schema.enabled}}, not so sure if
I understanding correctly. Would you add more description for this? But from my
perspective, this seems no needed.
*TestStateStore.java*
Also not sure this new test is really needed. I mean
{{TestStateStoreDriverBase}} may have cover these cases, for example driver
connection, etc.
*MockStateStoreSQLImpl.java*
Why we mock a new StateStoreSQLImpl that only testing for MSSQLServer? I hardly
see any difference between MockStateStoreSQLImpl and StateStoreSQLImpl.
