unit testing - How to reset the meta store with Hive on Spark? -


i want reset hive meta store hive on spark in unit test.

so far, i've reconfigured jdo use in-memory derby db:

system.setproperty("javax.jdo.option.connectionurl", "jdbc:derby:memory:metastore_db;create=true"); system.setproperty("javax.jdo.option.connectiondrivername", "org.apache.derby.jdbc.embeddeddriver");

there seems no proper life cycle management jdo in hive, hive/jdo complains if drop or shutdown database.

does know of way reset meta store each test case runs fresh, clean meta store?

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds
