Summary: Open time partition causes stackoverflow
Key: IOTDB-1207

Project: Apache IoTDB
Issue Type: Bug
Components: Cluster

Open time partition causes stackoverflow when use six nodes and three
replication
!image-2021-03-11-10-26-50-700.png!
After preliminary study,Find the problem occurs in the process of inserting
data to get the schema
Read remote schema in mRemoteMetaCache and if not all the schemas were
obtained, it will read local schema
before read remote shema ,it will try to get the corresponding device from
local
mNodeCache , If the device is not found, it will skip reading the remote schema
and read the local schema
because local mNodeCache dosen't contain remote device , it will never read
remote schema from mRemoteMetaCache ,this causes the insert execution
fail，forward plan failed,
and then will create timeseries for fail insertion,In this process, the
timeseries need to be created is empty ,it causes the process of creating
timeseries to enter an infinite loop。
In order to solve this problem, I removed the code that get the corresponding
device from local mNodeCache. but it causes another problem，When the amount of
data is large，benchmark will get stuck and occur timeout
