Unable to connect to Google Bigtable using HBase REST api

2024/10/12 12:31:58

Following this example, running the test script "python put_get_with_client.py" results in a 400 error (Bad Request).

So, I guess BigtableConnection does not implement the ClusterConnection interface? Is the example correct?

Answer

As mentioned in the comments above, we have submitted patches to the Apache HBase project to fix ReST and Thrift -- they've also been accepted and integrated. While we wait for a release which incorporates them to be release, we've released a temporary fork of 1.0.1 to help you work with this. We will be removing this fork as soon as these changes are incorporated.
