We build our data model with IoTDB's tag/attribute feature. The origin version is 0.11 and it worked fine with tag-based query. However, after we upgrading IoTDB to 0.12.2, we cannot query data with tag-based query any more. Although we can see our timeseries' tag information via show timeseries, tag-based query will return empty dataset. How to fix this?

This is an upgrading bug of IoTDB 0.12.2. You can compile the latest code on rel/0.12 branch of Apache IoTDB repository to use. This bug is already fixed and the bug-fix version will be released soon according to official statement.
