James Taylor commented on PHOENIX-2902:
---------------------------------------
Thanks for the patch, [[email protected]]. Here's some feedback:
- I don't think it's valid to set the IS_NAMESPACE_MAPPING_ENABLED or
IS_SYSTEM_TABLE_MAPPED_TO_NAMESPACE on the properties passed in at connection
time. We should just always do a remove for these properties. It doesn't really
make sense to switch the value at all. It seems to me to be a one way street -
once you've enabled it, that's it, it should stay enabled. You can just add a
constant in PhoenixRuntime for properties not allowed to be set at connection
time and remove those here in PhoenixConnection:
{code}
private static Properties filterKnownNonProperties(Properties info) {
Properties prunedProperties = info;
// If we find any properties not allowed to be set at connection time,
prune them here
for (String property : PhoenixRuntime.IGNORE_CONNECTION_PROPERTIES) {
if (info.containsKey(property)) {
if (prunedProperties == info) {
prunedProperties = PropertiesUtil.deepCopy(info);
}
prunedProperties.remove(property);
}
}
for (String property : PhoenixRuntime.CONNECTION_PROPERTIES) {
if (info.containsKey(property)) {
if (prunedProperties == info) {
prunedProperties = PropertiesUtil.deepCopy(info);
}
prunedProperties.remove(property);
}
}
return prunedProperties;
}
{code}
- I don't think this change should be made:
{code}

Otherwise, looks good.
