org.apache.hive.hcatalog.streaming.TransactionError: Unable to acquire lock on

[#1]

I am working on HDP Cluster and we are using StrictJsonWriter. We are getting below error while transaction commit.

Can Anyone help us why it is giving error?

writer = new StrictJsonWriter(hiveEP, hiveConf);

transactionBatch = connection.fetchTransactionBatch(10, writer);

transactionBatch.beginNextTransaction();

transactionBatch.write(inputFile.getBytes(Charsets.UTF_8));

writer.flush();

transactionBatch.commit();

transactionBatch.close();

connection.close();

Appreciate help in advance.

Thanks
