Question

我正在尝试关注Ring配置的Datastax Cassandra自学教程。我按照教程编写了虚拟机中建议的两个节点，但第二个节点无法闲聊。

我验证了listener_address，RPC_address，seed但无法配置环。以下是我收到的例外情况。

我还附加了Cassandra Yaml文件

的节点2：
Cassandra YAML：https://bitbucket.org/snippets/sreevastav/dL99d
Cassandra-env：https://bitbucket.org/snippets/sreevastav/on88p

收到例外：

Answer 1

更改Node2 seeds地址，使其与listen_address 匹配

# Compression to apply to the commit log. If omitted, the commit log
# will be written uncompressed.  LZ4, Snappy, and Deflate compressors
# are supported.
#commitlog_compression:
#   - class_name: LZ4Compressor
#     parameters:
#         -

# any class that implements the SeedProvider interface and has a
# constructor that takes a Map<String, String> of parameters will do.
seed_provider:
    # Addresses of hosts that are deemed contact points. 
    # Cassandra nodes use this list of hosts to find each other and learn
    # the topology of the ring.  You must change this if you are running
    # multiple nodes!
    - class_name: org.apache.cassandra.locator.SimpleSeedProvider
      parameters:
          # seeds is actually a comma-delimited list of addresses.
          # Ex: "<ip1>,<ip2>,<ip3>"
          - seeds: "127.0.0.2,127.0.0.1"

尝试从datastax教程配置Cassandra中的Ring
