Examples with QueryInfo co.cask.cdap.proto.QueryInfo used on opensource projects

Example 1 with QueryInfo

use of co.cask.cdap.proto.QueryInfo in project cdap by caskdata.

the class BaseHiveExploreService method getQueries.

@Override
public List<QueryInfo> getQueries(NamespaceId namespace) throws ExploreException, SQLException {
    startAndWait();
    List<QueryInfo> result = new ArrayList<>();
    String namespaceHiveDb = getHiveDatabase(namespace.getNamespace());
    for (Map.Entry<QueryHandle, OperationInfo> entry : activeHandleCache.asMap().entrySet()) {
        try {
            if (namespaceHiveDb.equals(entry.getValue().getHiveDatabase())) {
                // we use empty query statement for get tables, get schemas, we don't need to return it this method call.
                if (!entry.getValue().getStatement().isEmpty()) {
                    QueryStatus status = getStatus(entry.getKey());
                    result.add(new QueryInfo(entry.getValue().getTimestamp(), entry.getValue().getStatement(), entry.getKey(), status, true));
                }
            }
        } catch (HandleNotFoundException e) {
        // ignore the handle not found exception. this method returns all queries and handle, if the
        // handle is removed from the internal cache, then there is no point returning them from here.
        }
    }
    for (Map.Entry<QueryHandle, InactiveOperationInfo> entry : inactiveHandleCache.asMap().entrySet()) {
        InactiveOperationInfo inactiveOperationInfo = entry.getValue();
        if (namespaceHiveDb.equals(inactiveOperationInfo.getHiveDatabase())) {
            // we use empty query statement for get tables, get schemas, we don't need to return it this method call.
            if (!inactiveOperationInfo.getStatement().isEmpty()) {
                if (inactiveOperationInfo.getStatus() == null) {
                    LOG.error("Null status for query {}, handle {}", inactiveOperationInfo.getStatement(), entry.getKey());
                }
                result.add(new QueryInfo(inactiveOperationInfo.getTimestamp(), inactiveOperationInfo.getStatement(), entry.getKey(), inactiveOperationInfo.getStatus(), false));
            }
        }
    }
    Collections.sort(result);
    return result;
}

Example 2 with QueryInfo

use of co.cask.cdap.proto.QueryInfo in project cdap by caskdata.

the class NamespacedExploreQueryExecutorHttpHandler method getQueryLiveHandles.

@GET
@Path("data/explore/queries")
public void getQueryLiveHandles(HttpRequest request, HttpResponder responder, @PathParam("namespace-id") String namespaceId, @QueryParam("offset") @DefaultValue("9223372036854775807") long offset, @QueryParam("cursor") @DefaultValue("next") String cursor, @QueryParam("limit") @DefaultValue("50") int limit) throws ExploreException, SQLException {
    boolean isForward = "next".equals(cursor);
    // this operation doesn't interact with hive, so doesn't require impersonation
    List<QueryInfo> queries = exploreService.getQueries(new NamespaceId(namespaceId));
    // return the queries by after filtering (> offset) and limiting number of queries
    responder.sendJson(HttpResponseStatus.OK, GSON.toJson(filterQueries(queries, offset, isForward, limit)));
}
