Running ant in the root directory of Cassandra is yielding me a BUILD FAILED. I’ve tried with ant versions 1.10.11, 1.10.13, and the latest 1.10.14.

We are seeing read timed out exceptions in the application when we are trying to fetch the data with consistency level LOCAL_QUORUM.

I faced with problem due to connect two cassandra clusters placed in different datacenters. Each datacenter have public ip – lets assume there are 111.111.111.111 and 222.222.222.222. Cassandra nodes starts in docker contaners – 3 nodes in each cluster. The problem is clusters don’t see each other.

For testing purpose, I am using NoSQLBench to load the data on Cassandra 5.x. Its a 3 nodes cluster. I’ve noticed that when rampup(load) phase completes, the size of Bytes unrepaired reaches to the amount of data loaded / written.

When I run nodetool status this error is thrown:

Scenario: Number of Racks > RF (RF=2, 3 Racks)
Racks: R1, R2, R3
Nodes: N1 (R1), N2 (R2), N3 (R3), N4 (R1), N5 (R2), N6 (R3)

SyntaxException: line 2:5 no viable alternative at input ‘(‘ (SELECT usernameFROM [(]…)

SELECT username

I am trying to create a table in Cassandra and my query is the following:
