無法從Clickhouse連接到Zookeeper

Question

我正在使用適用於AWS的Bitnami Zookeeper AMI，並已配置了3節點群集。 我已經在我的Clickhouse配置文件中指定了它們，如下所示。

<zookeeper>
        <node index="1">
                 <host>X.X.X.X</host>
                <port>2181</port>
        </node>
        <node index="2">
                <host>X.X.X.X</host>
                <port>2181</port>
        </node>
        <node index="3">
                <host>X.X.X.X</host>
                <port>2181</port>
        </node>
</zookeeper>
<macros>
        <shard>01</shard>
        <replica>ec2-X-X-X-X.compute-1.amazonaws.com</replica>
</macros>

現在，當我嘗試在我的Clickhouse節點之一上使用以下查詢創建ReplicatedMergeTree表時

CREATE TABLE ontime_replica (Year UInt16,
Month UInt8,
DayofMonth UInt8,
FlightDate Date
)
ENGINE = ReplicatedMergeTree(
'/clickhouse/tables/{shard}/ontime',
'{replica}',
FlightDate,
(Year, FlightDate),
8192);

我得到以下異常

Query execution failed

Reason:
SQL Error [999]: ClickHouse exception, code: 999, host: <Clickhouse node IP>, port: 
8123; Code: 999, e.displayText() = Coordination::Exception: Not 
authenticated, path: /clickhouse, e.what() = Coordination::Exception

在我的動物園管理員日志中，我收到以下消息

2019-01-29 09:44:44,991 [myid:2] - INFO  [ProcessThread(sid:2 
cport:-1)::PrepRequestProcessor@653] - Got user-level KeeperException when

Answer 1

添加

skipACL=yes

在我的zookeeper配置中跳過身份驗證。

Answer 2

要使用登錄名和密碼連接到zookeeper，您應該這樣配置ClickHouse：

<yandex>
    <zookeeper>
        <node index="1">
            <host>X.X.X.X</host>
            <port>2181</port>
        </node>
        <node index="2">
            <host>Y.Y.Y.Y</host>
            <port>2181</port>
        </node>
        <node index="3">
            <host>Z.Z.Z.Z</host>
            <port>2181</port>
        </node>
        <identity>user:password</identity>
    </zookeeper>
</yandex>

更改配置后，您將需要重新啟動ClickHouse服務器。
