Ohara: Cannot run zookeeper with a volume

[eechih]

To Reproduce

1. Create and run a volume

{
    "group": "workspace1",
    "lastModified": 1594705145711,
    "name": "volume1",
    "nodeNames": [
        "ohara-dev-02"
    ],
    "path": "/home/ohara/data",
    "state": "RUNNING",
    "tags": {
        "displayName": "volume1"
    }
}

1. Create and run a zookeeper (dataDir type is Volume)

{
    "syncLimit": 5,
    "name": "workspace2",
    "state": "FAILED",
    "lastModified": 1594707079099,
    "electionPort": 38002,
    "xmx": 1024,
    "zookeeper.connection.timeout.ms": "10000 milliseconds",
    "imageName": "oharastream/zookeeper:0.11.0-SNAPSHOT",
    "aliveNodes": [],
    "initLimit": 10,
    "jmxPort": 38132,
    "xms": 1024,
    "routes": {},
    "dataDir": {
        "group": "workspace1",
        "name": "volume1"
    },
    "tags": {},
    "clientPort": 39792,
    "peerPort": 44232,
    "tickTime": 2000,
    "group": "zookeeper",
    "nodeNames": [
        "ohara-dev-02"

@chia7712 這個問題在 docker 和 k8s mode 都會發生 :(

我覺得要先確認 user name 為 ohara 並且 UID 要 1000, 才能建立 volume。確認 UID 指令如下：

# id -u ohara

我覺得要先確認 user name 為 ohara 並且 UID 要 1000, 才能建立 volume。確認 UID 指令如下：

[ohara@ohara-dev-02 data]$ id -u ohara
1001

@jackyoh 感謝 777 解惑

將 uid 改為 1000，這個問題就不會發生了。
