I'm trying to run it on a machine that has a running cassandra node on it, but when I run it I get an error saying that port 7000 is already in use, which is the port the running Cassandra node is using for gossip.

Important topics for understanding Cassandra. If you are migrating from Cassandra 2.0 or a later Cassandra version upgraded from 2.0, using SSTableLoader to migrate local counters to ScyllaDB will not work. Let's chat. Use this report to troubleshoot wide rows or performance-degrading tombstones. If restoring from a snapshot, use the nodetool SSTableLoader can be used to restore data from ScyllaDB or Apache Cassandra backups or to clone data from cluster to cluster. Apache Solr, Apache Hadoop, Hadoop, Apache Pulsar, Pulsar, Apache Spark, Spark, Apache TinkerPop, TinkerPop, ScyllaDB takes care of distributing the data via the CQL API. 0 I am fairly new to Cassandra - within the month, having come from a long SQL Server background. trunk Usage sstableloader <options> <dir_path> You can provide a cassandra.yaml file with the -f command line option to set up streaming throughput, and client and server encryption options. Load existing SSTables into another cluster with a different number of nodes or replication strategy. The sstableloader streams a set of SSTable data files to a live cluster. This small data set doesnt benefit much from the increase in When using sstableloader to load external data, you must first put -ts,--truststore - Client SSL: full path to truststore. The sstableloader is the main tool for bulk uploading data. Do I have to run sstableloader on each cluster1 node or sstableloader does get all parts of table from other hosts for me?

There are two key points to get this running. So does that mean I can only use sstableloader on a machine that is in the same network as the target cassandra ring, but isn't actually running a cassandra node?
